I like this quite a bit; though I do have a small issue with the framing of the shot... perhaps that is due to the brightness of the flash off of the white sheet, and the folds of the sheets on the bed being cut off. I do, on the other hand, like how all of the "stuff" is framed!
It's good that you did not split the image in the middle, and favored the floor.
The legs are certainly an interesting contrast to the chaos of "stuff" and I think it works.
Exposure is 7/10 just becasue of the sheets. Comp. is easy 8/10... overall I would say this is a very good shot and a great concept.
