Great coherence across the whole soundtrack, and i can clearly hear the different parts of the story. Just a few things that felt a bit off, like the way you use diminished chords that don't resolve in a satisfying way. I think there may be better ways of conveying mystery and suspense through harmony in juxtaposition with the happy feeling of carnival, or the reflective feeling of light. For example, in carnival, maybe instead of switching to a diminished chord you just move down a semitone.
Also, really like the tape vibe across the soundtrack! thanks for the fun listen!
