I much preferred the whited out eyes. Something very evil and creepy about them, if you're going to add pupils, maybe do something that isn't similar to human eyes. It just seems boring.
Well to be honest, I love the first, dirty, rough, unfinished version the best. It might just be me, but I think the roughness add some kind of charm to the piece. Or maybe it's just the fact that it doesn't contain the 2 elements recently added that I dislike; (pupils/lighting).
But I think you need to further emphasize that "I'm gonna eat your face right now!" look, and the first version seems to capture it best.
