Excellent composition for the brass, and you're actually using East West Symphonic Orchestra for what it was designed for. It's more useful for adding extra instruments to an already recorded track.
This sounds amazing, and the musicians you had to play your composition are astounding. I daresay this is one of those pieces that you could use to really show off to others ha. There's not too many flash artists who would turn you down when they hear this piece.
Great work, and I hope you will continue to record more work and submit it here!
