Her hair looks too random in the back. And I'm not liking her lips much. I'm not sure what it is, but they look too "pasted on".
The outlines on the eyebrows could lose some thickness, too. They seem too exaggerated.
The definition on her thumb is very poor.
Otherwise, I like the dynamics and movement, esp. the feinted movement in her clothing, done in a very uncluttered way.
