Very good.
That's a pretty damn good classical song you've got there. Just a few things though that I found bothersome. First, the background orchestra in the beginning (strings I thinks, but I cant' really tell : P ), the way it starts fades out then fades in is cool for a little bit, but then gets kind of annoying. I want to hear the entire orchestra play THROUGH the notes, not constantly drop out at the beginning of each measure. Still, an amazing piece you've created. And I like the way it loops, will work perfectly in a game. Good job = D
