Here are my two approaches to the Thing. First, the early, lumpy, rock version (he's very emo) and then a more fun (but still grim) cartoony version. Both done with brush pens. I love my Faber-Castell PITT Pens!
Orange Sharpie, green Faber-Castell PITT marker, black Motec brush pen, Presto! white-out pen, on Bristol. 14" x 7" I wish I would've figured out a way to get Q*Bert's feet in there. At least one of them, punching the gas pedal through the cubic floorboards?
