Haste

It may need a small eq(maybe less high mid)/filter adjustment thats just my opinion though, dubstep isnt really my favorite genre anyways, I like more of a progressive/edgy/uplifting sound these days. but i try not to let my taste get in the way of music critique :P

Just listened on my monitors, not on high volume though. Someone in my house is sleeping, but from what i can hear, the sub department is lacking a bit, needs more definition on the different notes it hits.

Or the high end of the track needs to be turned down a few decibels so the sub hugs the track more.
Again these are just my educated opinions and i dont mean to offend in any way, i figure i am helping you since you probably dont have 6 stereos to listen to it on to test it :P hope some of this helps.
