The bass needs some sort of limiter on it so it is not so overpowering. The chord progressions and melodies are well-done, but the basses need a bit of work. They don't really mesh well with the rest of the track or the drums. Instead of wobbles, you should try side-chained hypersaw chord progressions or something like that. Dubstep is not all 'bout them wobbles.

Other than that, this track has potential. Good luck in on your endeavors!
