Piano sounds real nice. Vocals are nice. Bass is sick, but the first beat just didn't seem to get me in the groove as the amen did.
Kind of was an akward drop when you went back to dubstep. I know it's a combo of 'em both but I think IMO is that you should carry on with the amen break.
That second drop out when it's just the bass should of been when the amen break came in. Make the higher freq's amped on the break. Everything else is at a high freq than what the amen break is at.
Other than that, nice edit.
