I had watched a documentary about the battle between Coca-Cola and Pepsi a number of years ago and I was fascinated by the different advertising methods they had used to gain their market share.
This was my simple way of showing how dominate Coca-Cola had become on the world market.
Conceptually it is good. I will leave the technical comments to others more experienced in product photography.
I don't get the feel of world market share from the photo alone. I know you were going for a clean surface and background, but shooting this on a world map or something to imply "global" would have helped me understand without reading the description.
A larger image with 100s of cans arranged in the shape of the landmasses of Earth could have demonstrated this as well.
Just my $0.02
