Nice hair, but...
The head is Excellent in itself, altough the right headphone looks like its on her hair and not the ear. The hands need more detail, the hand on the right looks like her fingers are coming from the wrist and her left hand is in an unnatural pose. Those legs are too short, they should be a little bit longer than the upper body where as you made them shorter. The neck also seems to be too wide, generally it should equal to the width of the distance between the eyes for a front angle.
