C&C.
As someone mentioned, the positioning of your key light is....well, key. In this case, I'd say that it was too far to your left and not high enough. Look at the shadow of her nose and it falls across her face. The shadow is just getting into her left eye and is going horizontally across her cheek, maybe even up a bit.
By raising the light, and maybe bringing it around to the front, just a bit, you can cause the nose shadow to stop before the eye and to be cast in a downward direction. If you move it high enough, you may even be able to hide that highlight on her lower left cheek, which isn't great.
Also, I think that the photo could have been improved if she had just pushed her chin/head forward (thus tightening the skin on both her neck and face) and tilting her head a little more to her right (accentuating a feminine pose).
Lastly, as mentioned, the highlight on her wrist isn't great.
