Did you use any photoshop filters for this picture? If so, not a good idea! From a photographic point of view, this image won't pass.
Have a read of this. It's a brief guide on image quality:
I agree with Ricky. Stock images should not have fancy filters applied. That decision should be let to the buyer.
For the rest: I love the fancy filter and the general composition, but I would not have submitted it to stock. In addition there is an error on the left leg and the face (or arm and right leg).
