I like the distorted harmonies at the beginning, but it started to get a bit too muddy-sounding for my tastes around :30. It's climactic, which is good, and, well, the dubstep bit- again, not really my style. The ending is a bit sudden, too, but it's interesting and unique to say the least.
Please contact me if you would like to use this in a project. We can discuss the details.
