Marvelous!
Really great stuff. Orchestration strikes me as very solid. The arpeggios in the piano gives it a really epic, inspiring feel and the grace notes notes at 1:19 and 1:26 add so much despite being a simple touch.
I'd give it a 10, but while the first 40 seconds seem 50 seconds or so sound more or less perfect, the woodwind feel quite intruding thereafter, though less so towards the end. The pitched percussion (can't for the life of discern what it is, steel drums? :S) also feels rather in-your-face. Still, I can only hope to be as good with MIDI orchestration and production as you obviously are some time in the (probably distant) future!
