You could do better.
Your background doesn't match the quality of models very well. A single one-colored plane that ends flat in the horizon? I know the girls are supposedly the main thing in this image, but a little more detail to the background wouldn't hurt.
There's something funny about the lighting of this scene. The girls don't seem to belong here - like they were teleported there or just cut to this background.
The texture on the skin is good though and the modeling is impressive. What's the triangle count?
