Here's a suggestion: do the flaming hair, not the regular hair, because the non-flaming original hair is ugly. It's like a chubby six year old's ponytail--or an ugly-lesbian-standing-up-for-women's-rights hairstyle. Ugh.
I'd also make the lips a little less ovular, it makes her appear to have a sort of mustache-ish lip because the upper lip... it's too large.
Moving up the nipples a bit so that her twins look more perky and youthful would be the best bet, but I'd suggest arching her chest a bit forward where her breasts are--as it makes her tits look like someone just taped balloons to her chest.
EDIT: This might help.
