I've always loved tree houses, but never got the chance of having one as a kid, so I've always pictured myself having a tall tree house as a studio, or at least being in one and sketching for just one day.
My approach was really trying to make a simple drawing, so I could not stress and overwhelm myself with the process.
First the sketch
With the color layers, I really feel I learned a lot about color theory, because it was a back and forth between the layers, and trying to figure out the opacity and how to mix to get the colors I wanted. It was really fun.
And then for the final drawing, I added some textures using the mask options and other fun texture brushes the Fresco App has. I'm more of a Procreate user, and never thought Fresco would be that fun to use.
I may do another version and refine the sketch, but I feel happy with the result because it was a really great study project.
