How? Who? What?... Help!!

I have been hired to do my first model shoot (other than the crappy graduation/ball shooting i do at work) and I am pretty in-the-dark when it comes to this sort of shooting.
The shoot is for a wedding lingere brouchure as well as the front cover of a pack of stockings (I thought I'd just kill 2 birds with one stone and do both client's ads in the one shoot! Using different shots of course) this is the 1st outfit we recieved so this 1st shoot is just a test run. I will have the opportunity to change anything I want for the rest of the outfits in the brouchure.
This is one of the 1st shots, it is the only one i have fully processed so far and I am fairly happy with it but i think it has far more potential, i just don't know how to access it.
I tried lots of lighting setups when i did them so i have lots of similar shots with different lighting if anyone thinks that could be the issue.
This is the attempt:
Shot with the D80, 17-55/2.8, 2 studio strobes (bought from Ronza's eBay store), one with a lightbox and one with an umbrella. The umbrella strobe was set to be 10 times more powerful than the lightbox in this shot so i could get the one-sided light and shadows.
Any help/comments/critisisms would be greatly appreciated
