OMG I cannot help myself, I just have to join this class project, I worked from the sofa/bed for a very long time back in my tiny flat, so perfect topic for me ;) Currently I do have a dedicated workspace but let's get back to the roots!
I luckily found the time to create an illustration especially for this class and I am happy to share my process.

My set up:
Since I have a tiny toddler running around the living room, working from the sofa was not an option, but I chose a comfy spot at the table.

My supplies:
To mimic the restricted space on the sofa I limited myself to only three tubes of watercolor (Sennelier yellow, Sennelier Opera Rose and Sennelier Dioxazine Purple for mixing the different shades of brown and rose) for the base layer of my painting and 16 colored pencils in total in different shades of beige, violet roses, yellows and browns to refine the watercolor base. I chose just one brush - a size 6 Princeton Neptune round watercolor brush and a piece of heavy weight smooth paper.

Reference: 

I chose a pink sweet cake for reference, because that's really what I needed painting to cheer me up in the current situation. Since I try to avoid unnecessary trips to the store due to corona, I wasn't able to get a physical cake but I guess cheering me up and making me feel happy serves the emotional bond suggested for the class project. On top of that, that's my second attempt to paint something that misses a bite - I still struggle to make that look realistic, but I like the challenge.

Process:
I first made a rough outline sketch of the cake (which I did not have a picture of, because I forgot) and after that I went in with my watercolor to create a base layer and let that dry. After it dried I wasn't happy with how it came out, because I had the impression that I went too cool with the colors. So I added another peachy tea wash on top of the glazing of the cake and let that dry again.
After it dried I went in with the colored pencils and refined my watercolor base, deepened the dark areas and lightened the soft reflections on the glazing. The most struggling was the crumbly area - as expected.
After I finished the painting I scanned it onto my IPad to remove the background, I also slightly like to tweak the colors, because they tend to fade in the scanning process.

Here are some process pictures - sorry about the bad lighting!

 

I had a lot fun with that project! Thanks a lot for this class project idea Kendyll!
