Nice shot. I wish that the shoes didn't have so much glare, and that the left one wasn't in such deep shadow. Also, I think it would look better if the shoes were more centered.
While the shoe in the center tooks crisp and bright and wonderful, the other shoe is completely lost to shadows. There is so much ppotential here, try shuffling the lights around or using white surfaces to bounce the lifght off so the shadow doesnt take over. Be weary of wherte your frame ends in camera.
