I’ve taught art for 11 years and what amazes me is how many times students just go with their first idea. The first idea is not necessarily the best idea. Here are my Deadpool sketches I’m working on for the upcoming comicon. My first draft, the head was too round AND I forgot to add the other katana. My second draft, I like the proportions of the head and I remembered the katana but the handles are different. I keep sketching until I come up with the right combination of proportions, details, pose, foreshortening, etc. ONLY after I’m happy with the image do I ink and color it. I left the correction marks on my second draft so you can see how my artistic process works. Hope this helps!
