Dude, this is cool! I'm loving the Afro-American Jazz era-style chord voicings here. The use of Grace notes to accentuate the melody and countermelodies beneath it works well. Creative chord progressions, and powerful transition choices.
I also heard you've got good skill with balancing and giving each section of the orchestra a "featured" moment within the work. Which is always appreciated by live orchestral groups, for sure. (I'd know! I used to play in one! Loved getting me a Trumpet solo that ended on a high D6 or D#6. Those notes, specifically, when played well by a trumpeter will just ring out and resonate well after the player cuts off. Love those moments, in my previous experiences. anyway, I got off track.

Overall, I don't think you've done a bad job here at all man. Props to you for getting out of your comfort zone to try doing orchestra work again. You have a knack for it, like many others on this platform do! 🙂 You fit right in, brother.
