I would have to agree with the guy below me

The wobble seems very out of place, I know its dubstep but there needs to be consistent harmony and rhythm.

Good, but needs work.

I really like the intro when the cross-melody comes in, but the drop isnt near loud enough and the oscilation rate on the bass needs to change more, maybe add in a few different bass synths.
I'd recommend listening to Datsik for ideas and/or inspiration bass-wise but you've really got something going, keep it up :)
