I've been working on creating characters that are in their own world. My wife, Rebecca, suggested to me to create monster characters as kids, because they are characters that everyone has seen before.
I sketched the characters individually on paper with blue pencil. Brought them into Flash and cleaned them up with the line tool. I brought the cleaned up drawings into Illustrator and changed the brush strokes using pre-made brushes. I then brought the new version back into Flash and colored them there.
