Step 2
In this step I make a very rough sketch.
Step 3
Now I switch to a cleaner sketch where I can see each color and texture will go.
Step 4
I select the color pallete to use in the illustration.
Step 5
Now I started a color sketch to see more integration.
Step 6
With the colors that were chosen, I finish the entire illustration without the textures.
Final
