well im no expert so you may want to disregard anything i say...
I'd say that the hair looks great. I did notice that it seems to give off a green hue which ( i think ) makes her look a bit older . And it looks like the front of her 'part' is a bit too thin ( you can see a bit much scalp ) I would thicken it a bit. Character looks very good as well, i like the style.
