The Wendigo is one of my favorite monsters, both as a plain ol' monster and as something with more of a complex backstory. I really like the creepy, distended look here. The face almost seems friendly, which makes it even creepier.
It's one of my favourites as well, ever since first encountering it as a child in one of the Scary Stories to Tell in the Dark books :)
