A couple things about this:
At 0:27, the warps make the BPM seem like it's 115, instead of the actual one.
0:35 is kinda harsh, try making the transition smoother, maybe with an increasingly louder drum buildup?
1:00... the dubstep seems really irregular and out of place. Try making it one consistent tune, which gets added onto. Maybe add some arps?
Good ideas, just need to be tuned up.
