Yea, he has no right eye. I've considered changing it, but it's been like this for years and it kinda hurts me just thinking about adding the other eye. It is rather troublesome, though.
I usually make a list of the things I messed up on or don't like about pictures I draw. A few of the things for this one are the head angle, the horns, the right hand, the legs, the pants, and the left arm.
Edit - I appreciate criticism. There's nothing I hate more than idiots who tell sucky artists that they have talent. If you think I suck, tell me.
