Woah, that's a creepy face! The way the left eye bulges (no shading) it looks even creepier. Some of the white spots look a bit misplaced, like they were just skipped in a rush to get this done. IE: all over the hair, at the creases in the T-shirt and throat. Looks a bit incomplete, but as is, it's a creepy face. Keep it going!
