HEY! Don't call her a jerk...I am sure she is a very nice girl! LOL j/k
I tend to agree...her legs look a bit orange to me. Did you happen to use the burn tool in ps and hit her legs a bit? I know that I have done that when editing and have gotten a similar result.
Also agree that there seems to be a problem with seperation from the bg. The lighting from the side suggestion is good...I would try playing with different light placements...side, behind, above...just try different setups to, as was said, give that 3D effect...
I couldn't find one exactly what I was thinking...but here is one that has a light directly behind the model giving that halo look and more seperation from the bg...kinda looks orange to me here too...maybe my eyes are orange right now...LOL
