While the blowing of the hair adds a bit of uniqueness, for me, I really need to see the models eyes to connect. For this shot, one eye is completely covered, and the other partially, which is blocking that connection.
it seems like this shot has really soft focus, or you did some funny editing. the eyes are the most important part of the portrait, they should be tack sharp. maybe try to focus a little bit more on that next time?
I think that the colors are good and that her expression doesn't seemed forced which is a good thing :) pretty model
