Looks very nice and I like the style, but there may be one problem...
The arm that comes toward the viewer then up to her head has a foreshortening problem, it looks ok from shoulder to elbow. but from elbow to hand it looks like it goes straight up instead of bending back to play with her hair. It would also help to have that hand shrink a bit to show some more foreshortening.
Foreshortening (for those who don't know what-the-monkey I'm talkin' about) is when someone draws an object that looks 3D (like when it looks like something is coming at you from far away to in your face) on a 2D surface (paper).
Besides what I've just said...DRAW MORE!
