I like the experimental vibe of this one. Interesting harmonies and a distinct ascending line on the piano. Combine that with the blissful flute melody, and the overall texture is rather atonal, but still feels dynamic and refreshing. Mastering is solid. I can hear all of the instruments clearly throughout. I especially like when the rhythmic pacing of the melody slows down at around 1:40 and you start experimenting with its range a little more. There are a lot of cool and unique melodic ideas here, but it still maintains a good deal of cohesion. In fact, it might even need more structural variety via a break in the frantic underlying patterns. The tranquil outro at 4:08 was a bit unexpected, but I liked it nonetheless. Really creative work here, guys! I hope you finish this one day. :)
