Wow! Some great instrument choices here, although I feel like Whispers Beneath the Canopy could have benefitted from stripping back to fewer instruments, to let the melody shine? It's almost hitting the same "epic" notes as the main theme, which feels a bit wrong (to me!). Your main theme itself, very well planned and structured - was thinking about where a human singer would breath though! And that last note, I'd definitely consider having lower harmonies to support how naked that high note sounds in context.
My heart was crying out for some filthy acid synth in the boss battle, and would have loved a cheeky solo woodwind in the piano reprise, or at least a growing and shrinking amount of reverb to tell more of a story through the piece.
But well done on completing this for the jam! Hope you enjoyed your time with it :)
