Here's today's doodle. I started out wanting to make his mouth creepy, although I didn't really follow through, so it ended up about halfway there. 3 hours start to finish, no reference again because i'm lazy.
Here's ol' frankie. I was thematically inspired by the ones that Jim and Samson posted, although mine went a different route. Maybe next time I'll try something a little more exaggerated and stylized. Somewhere around 7 or 8 hours.
