Track 1: Interesting mix here--this combination of instruments and sounds is unique. Definitely has me intrigued to hear more!
Track 2: I really love this orchestration, both tracks have such a unique sound! I can't think of anything to compare it to. That old, flutey synth is really cool too. Good job with this one.
Track 3: Really ominous track, I love how it just blossoms open.
In all, this is a solid soundtrack, and you did well. Keep writing!
