Wow. I thought that looked really amazing. The dolly shots were composed really well, as well as the rest of the shots.
If I can say one thing though, the first shot of the gun pulling out of the drawer, seemed a bit flat for the opening of a trailer. This is probably just a poor opinion, but it didn't seem as impressive as the other shots. Maybe harder more dramatic light would of looked cool, and if the tv remote was gone. Being only 16 myself, I don't mean to be a critic or pretend that I know what looks better or not, but it's just a thought.
Otherwise, the trailer was great, and I have to agree: shooting in B&W makes lighting seem a bit easier. Great looking stuff.
