A little too dark I think... With only one eye sparkling you lose the other eye almost completely... I'd have liked to see the brighter spot near her eyes rather than her chin and cheek...
Well done keeing so much details in your shadows. The lighting looks nice and soft. I think it needs more contrast/brighter highlights, though, even though it is low key. Your lighting is very well placed, IMO it would still be low key if you brought the highlights up, and it would have more impact. I wish there were a catchlight in her right eye, too, since it is the side that the light is coming from. Nice expressiong that you have captured.
