I like the model's pose and the overall composition. I don't care for the background which looks rather like a mattress cover. I don't care for the harsh lighting. The shadow behind her detracts as does the very bright spot behind her elbow.
I like the basic idea, and the red hair, orange sunglasses, and orange lights compliment each other nicely. It seems to be lakcing something, though - maybe a different arrangement of the lights, or even hiding her eyes behind the sunglasses maybe?
