You've got a really awesome sounding track here. I recommend that you really up the priority of the bass during the drop though. I suggest you push it to the front of your mix, or just up the volume. I understand the arp is the melodic focus of the song, and that's fine, but in a dubstep track it shouldn't outweigh the drop. The bass itself sounds really well made and well used, it just isn't loud enough.

Really solid job, dude. Just get that volume sorted put c:
