i think the lighting is interesting but the bottom right corner spoils the mood-might help to crop it out, clone it out, etc.-the problem is see with this shot is in their posture/body language-it's obvious they're cramped, which results in a slightly hunched posture
i would crop above the knee area but keep both hands in the frame. Like the light and color. Think the long legs bending to fit add to the awkward position.
Clever use the the reflector... I think the overall look if the models, cramped and all, fit the context of the location, especially the model on the right who has very apprehensive cowering body language. The one one the left looks a bit too relaxed and bored.... It would be a much more powerful image if you were to clone out the model on the left...
facial expressions are very uncomfortable (i don't mean to hurt your feelings with this comment at all and if i do i am sorry) they look like they are constipated
thats the only problem i have with the picture other wise i particularly like the background and the lighting
