Not misuse, Hooker. These are totally the same uncomfortable feelings that I get when I look at almost-realistic CG, and yet I'm looking at a real human face... I think.
I think his being cross-eyed doesn't help. He also appears to not be comfortable with whatever he's using to make his hair stick up half a foot from his head, as he's not moving his neck much if it can be helped, like he was balancing a book on his noggin. Maybe if he leans forward too far his hair will snap off?
