i like this a lot. i'm a sucker for minimalism. i also don't know much about dubstep, but from what i do know, it could use some more bass. you can add this to the kick, maybe. i also think the tempo change so be more drastic. like draw the notes out muuuuuuuuuuuuuuuuuuch longer than they were, long enough for the listener to "forget" how long they were and then boom, back to temp. just my 2-cents. i really this track though! super sick.
