Well, I love all of your picutres but this one is way too obvious the pictures r taken separately. Look at her shoulder next to that thingy that holds her dress, you can see the background. Besides around her face you used a brush that had a lower hardness and the light is not well either. So I'd put it under mixed media or photomanipulation rather photography.
Beautiful! But it looks like you used copy and paste. The line of her arm and shoulder does seem to sharp AND if I look very closely I can see a line of the background right next to her shirt strap (I donīt really know how itīs called in English). Itīs on the left of the strap.
