Not bad I guess, not a fan of the background just doesn't look like it suits it well. Also the quality looks a little bit naff but who am I to preach I don't even know how to use Photoshop.
Did you cut out the render? It looks like part of the wrist is missing haha. Asides from that I think it's decent however I would have preferred there being more flow with the hair going in the same general direction of the smudge instead of in a different direction. Also the part right beside the girl to the left where it is smudged upwards looks a bit out of place.
