Your file size is only 79k when you could have used up to 150k. This indicates a lot of JPEG compression, which is surely taking some detail out of your photo. Check the JPEG compression settings in your image editor and always try to save as close to the limit for a challenge as you can get it without going over.
Interesting concept here. A good attempt at a funky portrait set up, but maybe have be a bit noisy, pluse the lighting on the sheet next to her face creates a shape that to me is a bit harsh. 6
A good concept and great lighting, however, the white spot in the bottom left keeps catching my eye, and if she was lying on her other side, we wouldn't see the zipper.
Too much red. Since the background is in red it is hard to seperate your subject from the background. Does not give depth of field to your photo and it looks a bit of out of focus also.
