One of the first things I noticed was the clock. I saw the green cast in the background, but I don't see it on the model--could just be my monitor. So, I thought the green cast was intentional as a complimentary color to the red-orange lingerie.
I really like the mood and feel of the image, but I think the pose could be improved slightly. By having her right arm laying across her body, it creates a strange bulge in the tricep. Her left knee is head on which also makes that leg look heavier than it really is. By bringing both knees more toward her chest you would make the legs look more slender, and enhance the s-curves even more, and get the toes in the frame.
Very nice work, and although I can see a slight green cast on the legs, I like the overall effect. Here is an example of what I meant by the repositioning of the legs. Notice I cut off the toes also.
