Yea, I have seen this type of grungy minip too many times. Try somethin new and sexy.
But if you want crits on this piece, I would say to try and make the cracking on the skin surface actually look like the face is cracking. Also, the cracking going into the hair looks a bit out of place. I like the style, but it just doesn't seem like much effort was put into it, just looks like an eroded surface overlayed on an emo picture. The eye area is a dead giveaway on that, I just think it would look alot better if you concentrated more on the flow of the deterioration.
