I like this photo a great deal - it's all about opposites: green glass and pink shirt; cold drinks and warm skin; hard lines and soft curves; etc etc etc.
It may have its problems with focus, and the color may be off a bit, but damnit this is an intriguing photo. I think my favorite part is the fingers...yeah, the fingers. The cleavage is certainly evocative, but the fingers are much more interesting and surely more sensuous.
Hmm, what were you framing here? ;) An interesting approach, but colors could be better (yellow cast perhaps from wrong white balance), and more depth of field would help to keep the front glass in focus (I think the natural framing works better when in focus.)
A bit out of focus and the colours are too red in general. I would suggest playing with levels a bit to remove the reds and make it more natural colours.
Nevertheless I love the idea and your model is great for that shot.
