I love the composition, the lighting, her expression and the entire mood behind the photograph, however I feel that it's over saturated and that the contrast has been pushed too far to the point that it over accentuates her skin texture. As well, I am a firm believer that selective coloring is an easy gimmick and is only appropriate in rare circumstances, especially for portraits.
I would tone down the contrast and the overall vibrance of the photo that way you can take advantage of the soft lighting and show her good features in a more flattering way. If you look closely, there are areas of her skin that look very yellow and high in saturation, and to me this is not a good look for her.
When it comes to editing I am a firm believer that subtle editing will have the best results on a photo, and this to me has been over-edited. I think you will have much better results if you tone your editing down a bit.
