This is pretty epic :D! Loved the sounds and the groove feel of it!. The vocal sample is also very well used, and I luved the glitched effects. My only criticism would be that I feel like the drums should be varied a bit. It's pretty much the same drum pattern throughout the song, and I feel like the song would profit in having a bit more varied drum pattern.
Other than that, great job :D!. Keep up the good work ;). Been trying to make some dubstep myself lately, so it's really cool to listen to how other people do it as reference :D.
