Nice, but it's scary at the first.
Very clean, and loops nicely!
This is a wonderful friggin' piece of dubstep here. However, the only advice I would give at all is changing that crash at 55 seconds to something less generic and more electronic sounding IMO. Possibly some Love Philter or even just some vocoding with another sound. Otherwise, amazing work, fellow.
Shame it's so short...
