This track is pretty nice. It is pretty generic though. The lead was a tiny bit harsh, but that's dubstep I guess. The melody could have used a bit of variation, as it was very similar, if not the same, throughout the piece. The only other complaint I have is that the piano flams (not sure what to call them, so I'm using percussion terminology) could have been quicker/tighter. Other than that, the transitions are pretty nice and the mix is well done.
