Nice use of high key, but cutting off the glass seems to be a problem. I wish I would see darker liquid and less reflection in the Coke bottle, however.
Way too many people on this site like Coke. What's wrong with Dr. Pepper? :)
That having been said, I like you have a coke bottle and a coke glass. I haven't seen a glass bottle of coke in a long time, though I know they still make them, and it's much more interesting than the plastic ones in terms of a shot like this. The white background seems a little bright; maybe a countertop or a wooden table might have been better?
Nice use of overexposure, I would have liked to have the whole cup in the frame, is it cropped out for a reason? (the pixel dimension is only 500 across). Nice product shot -7- Mav
