You sure got the light right, and that scarf/pose is classic and beautiful. Nice job.
I did a little post editing on this (to removed a few things fotomann forever pointed out. Plus I saturated the red a little more, hope you don't mind.
I think alot of people might call that model "full figured" but i think she is lovely. I agree about the background though, perhaps losing some scarf in cropping out the edge would be worth it.....
Nice photo, but it's a shame the background wasn't wide enough. Perhaps you should clone in some black into that gap. Also, I'd work on a few spots on the floor.
