A lot of interesting ideas in here. Definitely reminds me of some of the piano work in BotW and TotK, particularly the trade-offs between sustained and staccato playing. Really dug Igice Theme - it has a kind of whimsy to it that is infectious.
I really dig the idea and execution of both of the Town themes - I think these kinds of opportunities in games should be jumped on to really add some charm and flair to events and progressions like these. Super solid piano playing in both, honestly.
Really liked the Great Canopy (Boss) theme - the emphasis on accompaniment is really well done here, and has a lot of Zelda-esque kind of melodies and choices of instrument voicings. Had this on loop for a few minutes just getting lost in the vibes. Sacred Marsh (Boss) is similar and is well produced and thoughtfully arranged, but the Canopy wins out for me, personally.
Final Boss is fantastic and absolutely nails the tone, very befitting of the title. A little bit of everything in this honestly, the choice of the early wind lead reminds me of some of the early 32-bit stuff out there, but as the track progresses the shift in rhythms starts to remind me of some more modern takes on underscore.
Great job with these - they're super solid, and kudos for producing so much in such a short period of time.
