Hair looks terribad, skin tone over chest does not match, should be evened out, and enlargement i don't see it, just looks pushed down and out. Text could be way better, wire frame needs to go, its distracting and doesn't match the piece at all. Err.. Idk i'm trying to come up with something positive and i cant find it...
I guess the body render could be worse you can still see some lines, but hey, no one is perfect.
Keep working at it, when dealing with hair, less is more, especially so it does not look weird and out of place.
