I think this shot would have worked better if the bottle and cans were in a light tent or box. The bottom halves are cut off and it appears that the bottle and cans have condensation on them. Visit the strobist blog, there is an article on how to build a homemade light box, it works very well
Great concept and a wonderful way to pull someone into the image. Shot strikes me as a little flat and could benefit from more side lighting. Is the reflection in the top of the bottle the camera and on-board flash?
