This soundtrack is really fantastic! The instruments are filled with emotion and the tracks have enough variety to keep my interest persistently. You've made great use of time changes, key changes, timbral difference, and the full range of the orchestra.
A personal favorite is the third track, Magical Undergrowth. The change into 3/4, and the reorchestration on the second loop, kept me interested the full length, and the chords are playful, unique, and fit the mood perfectly.
Confronting Moon King is another fantastic track. Your key changes are colorful, and keep the listener on edge. I love how you play with the main theme in almost each track, but bringing it back for the final battle is especially effective. I'm so inspired and hope you will keep up the good work.
