I like the music itself, but I don't think it would fit with the scene. It seems very tranquil and relaxed, when the trailer needs to gradually build up tension.The music would contradict the video and that's fine if it's used in an ironic way, but I don't think we could pull it off with a 2 minute trailer.
I agree with Simon. The music needs to be fast when the trailer speeds up. however its very well composed :). It'd be great for the futre or perhaps even at the begining
