Oooh, she really reminds me of someone - a celebrity, I'm guessing, but I can't quite put my finger on it. I think her strong brows are giving me a bit of a Keira Knightley vibe, though. She's got a cute style!
My one bit of feedback is that you might want to tweak your black hair color/swatch a bit. Making black hair look right in game is hard. It looks like you have a pure black (#000000) - or something close to it - selected for base/roots/highlights/tips which is basically masking out the hair's texture. I think if you lighten all the values a bit, you'll get back the shine and texture.
When picking the highlight color, especially if you are using adjust-shine, it can help to move the color picker towards a color (to get a bluish black, a warm black, etc).
