Those basses were SICK! They're so slimy and just.. really cool sounding :D
Unfortunately, I'm not too much a fan of the intro and the chords you used. The violin, I'm going to be honest, was not a good idea. I get you're trying to capture the idea of orchestral dubstep, but they're should've been more than just a violin in that case. As I said, I don't like the notes on the strings or piano, they're harsh and very unsatisfying. It doesn't match very well with the bass drop. I do have to give you props on such an amazing drop though, so 3 stars 4 u.
