the thing with the sculpt is i think the hair, it is a bit too flat. while the jaw is too long, it looks a bit strange when the hair is too flat. if they would put some more on the top of the sculpt, it would change the look of it and would improve it, i would say. i've changed it here a bit to show what i mean (again, i only put some more hair on the top):
it's still not perfect, as the jaw is just too long, but still better.
more improvement would make, if the face (eyes, nose, mouth) of the sculpt would move a bit down.
i've just moved the facial parts a bit down, not that much, and it almost looks better to me:
but i guess, this would be too much work to change it. but the hair shouldn't be that much work i guess?
