My friend Steve Wood drew this killer sketch at a sketchnight a while back. I went over it with Prisma markers to demonstrate how they blend, and to show how to add some darks for contrast into his coloring technique. The result was something pretty cool. He’s a fantastic cartoonist, and it was really fun being able to work over his drawing. I’d like to do more stuff like that.
He’s working on a blog right now, I’ll post a link whenever he gets it running.
