Heh, Sorry for the REALLY late review,
It hought it was pretty good, but the drum line needed to change as it went through, it always just the same drum beat. YOu need to add soem variety instead of layering and unlayering, other than that i thought it was pretty good. There was also a lot of tension in the song, but no climax to the tension to relieve that feeling, add a climaxing chagne of sound to help releave that feeling.
