I thought at first that this was a drawing of the character from "Indiana Jones And The Temple Of Doom". Then I thought it might have been someone from "The Princess And The Frog". Now I realize it's simply a god figure in Aztec mythology. That guy has appeared a lot in popular culture. He is pretty disgusting with the eyes in the necklace. They're pretty well cut out, I guess.
I like how you see that red pyramid in the background. It really gives off a feeling of gore. Interestingly enough, his expression doesn't seem that intimidating. He even looks kind of disappointed. Well, I'm certain he has a lot of blood on his hands.
