This was very pretty! I think you really achieved that underwater effect well with that reverb on the tracks, though i'm going to echo what other people have said and say it might be a little bit too much - it goes past the point of sounding distant and muted and instead makes the tail ends of all these notes blend together a bit, which makes it a bit harder to parse out what is going on. Overall this was nice though, keep it up! Ive never heard of waveform before this, and its always fun to see what people use.
