Awesome noise here at the beginning, really got me in the mood with this wind sample!
I'm liking the build up a lot, but I feel like the mix isn't doing 100% justice to the performances, my honest opinion would be to bring the piano and drums out front a bit more from earlier in the piece.
Nice melodies throughout, very triumphant build. Drum rolls are very cool here in the middle as well :)
What DAW are you using?
Thanks for sharing!
