Nice
Lovin' the wobble. Mind telling me how you make it? I tried making some dubstep today and the wobble is utter horrible. Do you use 3xOsc?
Anyways, on the song. I think you should work on the kick a bit. I hear a bit of 'bounce' in the kick which I found a bit annoying (my opinion). The snare I think, should have more high freq on it, but I'm a beginner at Dubstep so you might just ignore me here :P.
Overall, all nice and wrapped up for a WIP
