The Scene is set up quite nicely, my nit-picks are that the glass is a bit to clean for a beer that was just killed off (im assuming) and the reflections on the glass are too blurry, im not sure if the bottle is reflecting the sky or someone holding a flashlight near the bottle, but the textures on the packaging are nice, maybe add some wear and tear to them but thats all photoshop work..
nice render though.. I like.
