I think it looks great. Love the colors. The features are a little blurry, but that is not necessarily a bad thing. Sometimes impressions leave a lot of room for the viewer to project into it the rest of the image, and thus means they're invested in it. Good grabber. You've given a hearty push in the direction of this being the image of a real beauty and so the viewer will likely go there with it as well.
