the setup - two ancient Bowens mono lights with umbrellas (cross lighting, for "loop" shadow), and two large white baffles to bring the contrast down. Pocket Wizards to trigger everything...
There seems to be some pretty substantial background shadowing though, and in contrary directions. Perhaps you could have her come out a foot or two more from the screen?
the shadows to her left aren't really apparent in the photos from the shoot, and the shadows on the background - well, that's a question of "art director taste", sigh...
