great job
I really liked what you did with this peice. Bach is also my favorite classical composer, so props for that too lol. The only thing I don't like is that you used FL slayer. If you ever need a guitar part done, just shoot me a PM, I'd have no problem doing the parts for this song or anything by you.
A word of advice, don't put this in classical, it will never get the recognition it deserves. I'd probably put it in hip-hop...even though it pains me to even think about it.
