Like this shot. Good lighting, interesting setup and good pose. Would have preferred not to be able to see the panties. Just the low cut jeans in the same position they are now would have been pretty damn sexy. Great shot either way.
I definitely like this photo. I agree with you that the background IS important so I think if you choose to leave stuff collecting on the top shelf let them have some meaning. Build the scene entirely...like a bottle of Jack Daniels or good scotch in the background or something that adds to this already fine picture. (That said I know what a bother it is to have fuss with the scene and the wardrobe when you really just want to get a good shot.)
