You need to work on your side profile a bit. Her nose is a bit too... I dunno. Also the bridge of her nose should be more inwards, and her forehead should have more definition. Something's up with her chin as well..
To give a clearer picture of what I'm trying to say, here's a anime profile similar to yours for you to look over:
The hair could definitely use more detail, and the highlighting isnt great. The shine of the hair should go with the shape of the hair itself... not just a line of white across the hair.
Example:
The shading of her chest gives the impression of very lop-sided boobs... I'm sure you didn't want to know that, but I'm just saying what I see. I also don't really know what's going on with that line going down the center of her chest/abdomin. The way you shaded it makes it seem like there's a big crack going down her front.
Yep. That's about it. You have some things to work on, but it's a good start.
