Great tune man! I'm really digging the house bit. I have mixed feelings about the dubstep in there though. A lot of people think you just need to play with the filter, but you've also gotta change the timbre of the synth. Play with the saturation! Add some redux or erosion to give it that "yug yug" quality. If you're using ableton, a beat repeat can add a lot of neat variation to it. Just break out of that standard cookie-cutter wub-wub-wub to really make this track shine. Great piece though, and I'll definitely have to check out your other works.
