Track 1: I love the modal melody here! These synths are really beautiful and pure, and I enjoy how they gentle reverberate. Quite a lovely opening track!
Track 2: cool soundscapey effect here, and really nice chill beat. I like the length of this track: not too long or repetitive, just a moment of chill beauty.
Track 3: Quite a cool sound! I love the contrast of the low and high voices in the synth. The sparseness of this track is super effective-- you have really great melodic lines, and don't fluff it up with extra stuff.
Though short, this is one of the better soundtracks I've yet heard. I was really intrigued the whole time and absolutely enjoyed listening to it! Keep writing!
