Potential to be greater
You've got some really great sounds in here and the beat really pulled me in at the start. Unfortunately, I found that the denouement was a little clouded and subdued. The way the beat sets you up at the beginning makes you expect some crazy melody or wall of sound, instead presenting you with a little loop.
Other than that, I would advise to work a little on the timing of integration, but otherwise it's all good. There's some really sweet samples in there and it works as a song; I just feel it could be a little more controlled. (Controlled chaos? ;P)
And I just have to say again how awesome that beat is at the beginning.
