I like the distorted atmospheric part at the beginning. The percussive thing that plays on every off beat starting at :13 was a little much. It basically functions like a snare, yet sounds more like a transitory effect. The build-up wasn't bad, but the drop at :53 sounds really distorted. You may have used a bit too much reverb there. Despite all the reverb, the drop is also quite minimal from a harmonic standpoint. I like the mechanical sound effects at 1:54, though. I appreciate the variations on the second drop, but in general this piece has very little in the way of harmonic depth, which is probably my main complaint. It's a well-structured and smooth-flowing piece with some unique sound design, but I think you need more moving notes in there to offer the listener a more memorable harmonic framework. Keep at it, man!
