I like the setup on this picture. It would be nice if you got in a bit tighter to really enhance the bottle as the focal point in the picture. The ocean background is a really nice touch.
Seems like a lot to look at and the beer bottle isn't providing that much impact. What might have been cool is to come in a little tighter, move the bottle to the right some, and get more of the people in the background in the water and on the beach. JMO of course. Good luck in the challenge.
6: Oh no, the bottle is falling! A bit of rotation to straighten the bottle would help. I like the way the pier in the background runs off into the distance.
Should be a girl in a bikini in this picture. You don't sell beer by showing a mostly empty beach. You sell beer by showing healthy, sexy people frolicking on the beach. Nontheless, this would work a lot better if the beer itself were standing straight up. Perhaps you'd been drinking it before taking the shot, eh? Admit it!
I like the concept here. Comp is nice and would work well with possible text. Lighing is nice and DOF gives just enough detail while displaying product nicely. However, A tighter crop would bring the product into a more Prominent role. The bottle shouldn't be titlted either.
