Superb composition. Exceptionally appropriate. My only critique is the virtual instrument one, where its clear that given the time constraints, there isn't enough time to do all the cleanup and tweaking of dynamics to make them sound natural. Sometimes a bit of a high quality reverb cranked up a bit can help blend some of the VST sound.
Heh, I'd love to sing on a soundtrack like this to tie some instruments together. One of my favorite soundtracks is from the movie Hero. That might even be my favorite soundtrack of all time, can't decide between that and Lord of the Rings. Anyways...
Really good work. If you can find more ways to break out of the "VST" midi sound, you'll be creating top-notch soundtracks.
