The Songstresses: Your collection of instruments used feel authentic to the theme image and to the world you are creating. Even with a slower tempo, it keeps the energy moving when you hand the melody from one instrument to the next. I am a fan of the whimsical yet contemplative sound particularly conveyed by your main melody.
Songbird: The flute ostinato is catchy and its repetition makes me think of the songbird kind of like Navi from Ocarina of Time. This track reminds me of some dynamic LittleBigPlanet music in how it is constantly evolving throughout while keeping a solid core identity.
The Mountain: Those big swells at the beginning using those big major chords give a sense of grandeur and immenseness which makes me think of ascending a big mountain. The shift in feel to a much more intimate sound with pizzicato strings is an interesting choice, but I imagine has story-driven importance - possibly for a searching theme when they reach a meadow or clearing high up on the mountain. That’s what I imagined at least!
Man: Hey, we both used singing bowls for our final tracks! They create an almost spiritual sense that helps create a gravity shift in the story. The foreboding and ominous chord progression makes this fitting for a villain or danger theme.
The progression from mystical to light-hearted to expansive to searching to ominous while maintaining a cohesive sound helps clearly direct us in where the story is going and helps me follow along. This overall was an enjoyable listen. Great work on this and thank you for sharing your music!
