Very nice.
The choirs sound very good. Actually better than most of the other instruments :P I have some minor quibbles with your timpani, I thin a loud and massive, bassy grand casa (or whatever it was named) sound would be better for this. Anyway, very nice progressions, I like this one. And it's long (since you have two parts of the song too).
Keep up the good work. You get a 9/10 and a five ( 4.39 / 5.00 (+ 0.0048) ).
