I really don't think charcoal is the best medium if you're going to draw teeth. Eww.You definitely need thick skin if you're a celebrity -- I think some of those would hurt my feelings! :)
Hahaha! Those are downright scary! The second one made me think of the cartoon Quasimodo. :D
AGH! What's on the side of Will Ferrell's face? And why do all the ones with teeth look like vampires?
Because these 'artists' skipped the day when they were taught to neither delineate nor shade individual teeth. The subjects look like they're eating mud.
These are destined to become bad tattoos one day. Mark my words.
