This shot has a lot of potential I think. The overal composition is good, and the idea is hilarious. First, the white balance seems to be a bit off -- it looks like it has a yellowish cast to it. Secondly, maybe if you could crop closer and leave off the bottom of the can and the sides. This woudl give it an almost infinite feeling.
hmmm...judging by the fridge you must be a bachelor. :) Nice set up, The left side is a little darker than the right but I'm sure the lighting inside there is difficult.
