1. Intro: You have some colored pencils lying around and 5 minutes to spare, then bear with me. Hi, I'm Gabriela Shel, an illustrator and concept artist. And today's class is all about quick, fun thumbnail sketches made with colored pencils. Most of us already have colored pencils at home, and there are so many practical benefits to painting quick thumbnail color sketches without the pressure of longer painting. Just 5 minutes a day can help you break from the perfectionism trap, train your eye for composition and color harmony, teach you how to simplify complex subjects into loose sketches and help you effortlessly build a consistent art habit. And most importantly, they are really fun to paint. This class, we will be creating quick and fun five to seven minute color thumbnails together. You can choose to commit to doing one sketch per day as a quiet morning ritual, or you can sketch several at once in a signal setting. I will walk you through how I organize my materials, how I work with references, and my dot process while I work. So grab some pencils, a piece of paper, and let's start building your art habit today. 2. Class Orientation: In this class, our main focus will be creating a series of quick thumbnail sketches without the pressure of producing a complete or perfect painting. We want to have fun with these quick solor sketches and in the process steadily improve our art skills by building a consistent habit. For the class project, I encourage you to create your own five minute sketches. You can choose to create one per day as a part of building your daily sketching habit, or you can paint all of them in a single setting to make things as easy as possible for you to get started. I have put together a Pinterest full of beautiful vibrant reference photos, which you can find linked in the resource tab below. So you're also more than welcome to use your own photos if you prefer. I want you to grab a piece of paper, quickly draw six rough little frames, and tackle these studies one by one. One of the most important things here is to avoid getting caught up in details and overworking your art. For that purpose, make sure to have a watch or timer on hand to keep the sketches at five to 7 minutes each. Remember, the goal here is not to create a polish masterpiece, but to train your eyes, simplify the shapes, and actively practice letting go of that perfectionist mindset. So go ahead and open that reference board, and let's move on to the next lesson to talk about our materials. 3. Materials and Preparation: Let's take a short moment to talk about all the materials you will need for this class. Colored pencils are a medium which is oftentimes put away in the category of children's tool right away, apart from some excellent artists who use them for realism style artworks. I wanted to get away from that and start using colored pencils more extensively because they offer a certain freedom from perfection, which we oftentimes fall into with other mediums. I grew quite a big selection of colors over the last few years, as I've been buying additional colors separately from the sets, and I use them extensively to do quick sketches or as an additional tool to other mediums such as watercolor. I use mostly polychromos for fiber castle because I think they're wonderfully pigmented and easy to work with. What I also really appreciate about them, especially when working on speed paintings or thumbnails, is that you can see the color right away because the whole body of the pencil is colored and the color of the lead itself. But I also use other brands or series which I have at hand as long as they have the right color I need. So for example, I will use watercolor pencils alongside normal pencils or even some cheaper sets I found among school supplies. That being said, for this class, you can use literally any colored pencil brand you find because this class is not about perfection or high pigmentation or the end result per se. I have successfully used school grade colored pencils for my thumbnails, as well as high end professional pencils. So just use what you have at hand. What I do recommend, though, is to have a wide range of colors available, since we will be working quickly, and it's quite useful to have the colors at hand without having to layer too many different pencils to achieve the tone you need. I like to organize them by color groups, so I have them ready, mostly grouping them by yellows, reds, blues, browns, violets, and grays. I also like to use a utility knife to sharpen my pencils, as it gives me a better point than a normal sharpener by allowing me to create a flat edge, which is great for quickly filling in bigger parts of the sketch. I also use an eraser to remove some excess colors if needed, and I also have a normal pencil for my outline sketching. I'm not really picky with my paper either. I've sketched on normal print paper and even on bigger school grade paper rolls. For this class, I'm using this Canson mixed media paper because I like that it's somewhat thinker at 200 grams, and it has a nice texture which makes it easier to layer color. You don't need fancy paper for this class, but using a somewhat ticker paper will definitely make the whole process much more enjoyable. For this class, you will also need the reference board I prepared for you on Pinterest. To you're also welcome to use your own reference if you prefer. I like to open them on a computer or my tablet nearby, and I actually leave the whole board open without clicking on the single images because keeping the reference images fairly small forces us to ignore the tiny details. Since we want to paint thumbnails, we want to just focus on the main parts of the image, such as the overall composition, the colors, and the big shapes. Also really recommend having a watch or time nearby to avoid overworking and spending more time than necessary on the sketches, as I usually recommend spending around five to 8 minutes on each. So grab your favourite pencils, sort them out to make it as comfortable as possible, and let's get started. 4. Demo 1: Coastal House: So let's start with the first demo, and to begin with, let's start with the simpler one. I have my reference image open on the computer, and I will also add it here to the screen so you can see exactly what I see. I have all my materials ready and my colors organized. And while you can pre select the colors you plan to use for a certain image in advance, I personally prefer having them all at hand. I'm going to quickly pre sketch the frames of our thumbnails today, and of course, you could use a ruler to make it all pretty neat. But usually, I just sketch it free hand like that or even start right away without any framing at all. Once you have the frame, you can use a graphite pencil or just a light colored pencil to sketch your rough outlines of the image. I like to make a very rough, quick sketch before I dive into the coloring process per se. So I have some basic outlines to guide me, mostly focusing on the horizon line and the overall structure of the objects. A good piece of advice I learned when I was in art school is to try and see the shape of the object by focusing on the outline against the background, basically, as if you were trying to paint a negative space. When sketching buildings, it's also important to pay attention to the perspective lines as nothing can break the believability of your sketch quite like bad perspective. Once I have sketched the outlines, I continue right away with filling in the color, and in this case, I'm using a brick red color to paint the roof. As you can see, I'm placing the marks following the direction of the roof. Following the form with your line placement is a very useful trick to instantly add texture and emphasize the form of the subject in your painting. Then to put the colors directly into relationship with each other, I'm coloring the soil, which consists of several different shades of ochres and some oranges to add some warmth. Here again, I place the line horizontally to further accentuate that plane. The great thing about colored pencil is that you can easily layer them to achieve the exact colors you need. The sky is somewhat grayish, so I am using a mix of blues and grays to capture that feeling. You don't have to have the exact same color I have at home, and I really recommend you just use the colors available to you because this is all about training your eye and choosing the colors that speak to you. If you add a color and see that something is off, you can either erase it or just layer a different tone over it to create the hue you need for the sketch. And we can also see a little bit of the sea behind the building on the horizon. So I'm using my blue to add that. A few more touches, and we are done. So let's move on to the next one. And 5. Demo 2: Tuscany: For our second demo, let's paint a cozy Italian landscape. I will use my gray pencil to sketch the outlines. It's generally a good practice to quickly determine the main colors of the scene and use that one for your initial outlines, although you can also just use a normal pencil. The scene has quite a few more elements and a very nice road that kind of disappears into the horizon. So I am taking a little bit more time on the initial drawing in this one in comparison to the last sketch, as we have a very interesting composition to capture. For one, we have this S shaped road that disappears into the distance and some very interestingly shaped trees, while in the background, we have different layers of fields followed by mountains and beautiful clouds. I use ochre to lay down the fields. Since we have a lot of vegetation which naturally points upwards like fields or weed or grass, I am using an up and down movement when adding color so we can create the texture naturally with our strokes. We have some horizontal lines in the background, which I add as well. And then I use a cooler brown tone to sketch the road, using the same principle of following the direction of the road with my line to strengthen the feeling of perspective. Uh, Let's also add the shadow on the road from the vegetation. I use an olive green to paint the lighter parts of the trees that catch the light and a darker green for the shadows. Though in hindsight, I'm actually not too happy with the color I chose for the shadows. Which is why I am just painting right over it again with my olive green to soften the hue. That's actually the exact reason why I keep a piece of white paper lying next to my canvas. So I can use it to try out colors and see if I like them before adding them directly to my sketch. I use a darker ochre to add more definition to the fields and the grass, and I like to imitate the texture of the fields in the background with some lines that also help to show the depth of the scene. Now, moving on to the mountains, they have a very distinctive blue tone in the distance. And since I don't have that exact color pencil, what I like to do in this case is to start with a color base. We have very beautiful clouds in the background, and since we cannot actually paint white on white paper, the best thing you can do is just leave the white of the paper as it is and paint roughly around it to add the feeling of the clouds. I layer an additional color to my mountain range to create the hue I need. I also add some more Acrashadows to mark the road and Walla We are done in a bit over 5 minutes for that one. So let's move on to the next one. 6. Demo 3: Tomatos: Change the subject somewhat and paint the still life for a change. In this case, a beautiful photo of tomatoes. I am using my pencil to sketch the outlines first. We have several elements here, including the spherical tomatoes in themselves with their stems, the white striped kitchen clothes, and a warm brown background. Since it's quite hard to fill in color while maintaining a perfect circle when working fast, I like to draw out the outline of the tomatoes before I start laying down the base color. A good practice is also to determine the lightest parts of the image. Apart from the lighter cloth, we also have the highlights on top of the fruit. You can sketch little circles on the spot to remind yourself to keep them white when coloring. So now I'm choosing a matching red tone and paint the tomatoes with it. Being very careful to leave the highlights areas completely white, being very careful to leave the highlight areas completely white. Ds After that, I choose a darker red tone and start adding darker values, especially in the parts of the shadow area. This is a really great exercise in learning to see colors and shapes. And if you pay close attention, you can actually see reflected light bouncing back into the shadow side of the tomatoes. I use olive green to paint the stems, which for some reason, I love using for most of my greens, but anyways. For the cloth, I use my light gray pencil to make the bright tomato stand out more. And luckily, I have a green pencil for that. It's very similar to the reference image to paint those stripes. I I also paint the background of the image with a brown. But right now, the image still looks quite flat because we or cast shadows. So let's add those in. The shadows falling below the tomatoes have quite a warm tone to them because the red from the tomatoes is actually affecting the hue of the shadow. So I use a brown next with red to add a warmer uter. I also add some more intense reds to the tomato itself, especially on the edge where the light transitions into the shadow because it instantly creates a more t dimensional look when combined with those shadows underneath, because it instantly creates a more three dimensional look when combined with those shadows underneath. I could keep on working on the clothes and adding more details, but that is exactly not the purpose of this exercise. So I will call it done, and let's go for the next one. 7. Demo 4: Portrait: Let's see how you can apply the same speed painting principles to a portrait study. I really like this reference image because it has some cool geometric shapes and great color contrasts. So I'm taking a bit more time to sketch the figure as we need to take the proportions of the head into consideration. I just want to remind you again that it's really not important to be perfect at this stage, because this is all about training your eye and your hand, learning about color combinations, and learning to let go of perfectionism. After sketching the outlines of the figure, I like to fill in the most obvious parts first, which in this case, is his shirt. I use Payne's gray as a base and add a bit of a darker blue to it. Now I go for the orange circle in the background. As with the tomatoes, I outline the circle first with my orange color and then painted in carefully as orange is not the easiest color to erase. Now I add a yellow tone to the wall in the background as a first color. To darken it and to make it a warmer hue, I add a flesh colour tone. I do this because I don't have the right color for the background right away, so I have to get a little bit creative mixing it. I use the same flesh color to add a color base in the face. The shadows are quite warm in the tone, so I use a brownish red to mark the parts where the shadows of his face are. It's somewhat like a brick color, and I use it quite a lot. I like to quickly map out the major shadow areas of the face, which are the eye sockets, the nose, and the mouth area. And if, by the way, you want to learn more about portraits, I actually have quite a few classes with the portrait focus here, so feel free to check those out if you want to learn more portrait basics. Portraits are generally considered to be more complex subjects because you have so many different subtle hues and shadows and shapes working together to create an illusion of a person. But again, the whole goal of this study is to keep it loose and quick, so I will actively avoid overworking it at all costs. After the brick color, I am slowly deepening the darker parts of his portrait. I chose a brown to paint the hair, beard, and also marked the eyes and eyebrows. I also like to layer different intensities of colors when I work. So, for example, I first left the shirt rather light and then added more strength and darkness later on, always making sure to compare how my image looks in relationship to the other colors of the page. Since I used mostly warmer colors for the portrait, I added some darker shadows with my dark blue, especially in the eyes, eyebrows, and the hair. I strengthened the oranges as well, and also added some more shadows on the background itself. I also decided to add some more colors to the skin tone, but in my opinion, the okra wasn't the best choice here. So I will leave it as it is, since I'm already at seven minute mark, and I don't want to overwork the sketches. So let's move on to the next sketch. Oh 8. Demo 5: Lighthouse: Paint a beautiful atmospheric lighthouse for our next demo. I again use my pencil to draw out the horizon line, the outlines of the lighthouse, the rocks, and the sea. Here you can see how I'm using my additional scrap paper to test my blue colors before I commit to them. I have so many blues and there are so many different blue tones in the reference image. So I wanted to make sure I am choosing the most matching colors. I start by filling in the sky using horizontal strokes to sketch the blues of the sky, keeping it super light at the beginning, because I will be continuously adding more and more strength to the colors as I keep working on it. For the Sea, I am using a different type of lu. I use ochre for the base of the rocks, and it's generally a good idea to work from light to dark when you use colored pencil when you use colored pencils. So since we have quite a few lighter browns and aqua tones in the sunlit part of the rock, I make sure to sketch those in first. Now, I switch to a darker brown and start defining the heavier shadow areas of the rock formations, varying the direction of my lines when I do so to help create some additional rugged texture. I use horizontal strokes to paint the water, paying special attention to the whiter spots in the sea where the foam breaks against the rocks. As I paint, I'm switching between three different blue colors, adding more color variety, and depth as I go. I leave those foam areas mostly untouched, and instead, I use different blue shades to darken the sea around them, and you can really play around with different colours here to see what turns out and which combinations you like the most. I am also adding some vegetation using aqua and greens to the rock formation. Oh. The lighthouse itself is white, so we will preserve that lightness of the paper and only paint the shadow side of it, as well as the red top. I'm not even sure the top is red, since I keep the reference image so small, but I don't actually care that much about it. I think red will do great on this color composition and add another colorful element to the sketch. The lighthouse also has a nice little house structure sitting next to it. So let's add that as well. And remember, it's your sketch so you can be creative with it and add and remove elements exactly as you like. I feel like I left too little white where the foam part is, so I'm using my utility knife to cut a sharp piece from my eraser so I can easily erase smaller parts of my sketch to bring those highlights back. I could have left the parts completely white as I did with the tomato sketch by marking the area with my pencil beforehand. Another way to make the white send out more is to darken the area right around it. So since we have a darker area below the rocks where the shadow falls on the water, let's darken that a bit to push the contrasts. We are nearing 7 minutes already, so I will call it done. I think I captured the likeness nicely, and it was also quite enjoyable to paint. So let's move on to the last sketch. Two 9. Demo 6: Rooster: Change of pace, let's paint an animal, and I found this really gorgeous reference of a rooster. Before you start painting, it's always a good idea to analyze the reference image for a moment. And here we have all those beautiful orange hues in the body of the rooster with some reds and dark blues and grays in the tail, all set against a bluish background. This is a really nice color contrast, which is naturally going to make the image pop. So let's get started. I use a pencil to sketch the outline of the rooster, and here again, it's a great idea to focus purely on the outline of the shape against the background rather than trying to decipher the complex anatomy of the bird. Just pay attention to the shapes the rooster creates against the frame of the image and the background and sketch those in. I lightly erase a bit of my pencil line art as I don't want it to be visible under my final sketch. I start with the background using a dark blue color, and since we have horizontal lines in the background, I add those using horizontal strokes. Below the blues, we have a browner patch where the light has fallen behind the rooster. So let's add that as well. Now moving on to the rooster itself, I am adding a yellow undertone under the whole animal first. With an orange pencil, I'm marking the shape of the wings and the breast, using the same directional principle we talked about in the other drawings by trying to follow the natural direction of the feathers I'm painting. This painting is basically a rich mix of oranges, browns, and reds, which we just have to layer until we reach the depth or color we need. Tail, I use paints gray, which is my absolute go to shadow color. And with a warm brown, I'm painting the shadow area of the breast and under the body. We have some really nice reflected light in the shadow area of the breast, which is light that is being reflected from the brighter spot on the floor and bounces right back against the rooster's belly. I darken the background progressively, and if you look closely, you can see how the oranges and the yellow start popping out more and more as soon as I darken the space around them. As I go, I add some darker and more intense browns and oranges to the rooster. And that's it, or last one is done. 10. Final Words: Congratulations on finishing this class. You can be really proud of yourself on having started something today. I hope you found this little class useful and encouraged you to create your own sketches. By setting a limited time frame and choosing to work small, you've captured the essence of six completely different subjects without letting yourself get trapped by perfectionism. Throughout these demos, we practiced how to simplify complex shapes, how to find color relationships quickly without overthinking them, and how to use our pencil strokes to add texture to our sketches. I hope this class has shown you that you don't need to have hours of free time to create beautiful art or to improve your observation skills because doing those five minute thumbnail studies is a fantastic way to warm up your hands and train your eyes before a longer painting session. For your class project, I would love for you to create your own page of five minute colored pencil thumbnails using either the reference images I provided or any images that inspire you. Remember not to worry about the final result and instead, just focus on the process, playing with the colors and sticking to that time limit so you can really embrace the process. Please make sure to upload your thumbnail sketches to the project section because I absolutely love seeing your work. If you enjoy drawing with me today, please leave me a review as it really helps out. Feel free to check out my other classes here, and thank you so much for joining me. See you soon.
