This is my second project using Sketchbook. The Hulk was drawn by Joey of Average Joe Art. I laid down the flat colors and then he shaded it. Both of us are HUGE comic fans, so when he decided to do a bunch of Avengers themed art I was all for it! I didn't know how to shade when I drew Deadpool. So I learned a little about shading and changing the opacity on certain areas with the Hulk. Not a bad team effort eh?
