This is really very nice. I like the bottle caps too. There's one thing though. You used softshadows and glass, but you didn't render in Premium-mode. The result of that is the stripes on the bottles and the lines in the shadows. These artifacts are gone as soon as you use premium-mode. Problem is that rendertime will skyrocket. It's up to you to decide if you find the rendertime that comes with premium too long.
