beautiful soundscape! The whole first half was extremely good! Then at some point it became as if you weren’t sure where else to take the music, and it kinda came off clearly.  I think what you could have done is keep that whole beginning, then at that point where it became confusing, use as a whole new section and make it obvious that you aren’t just trying to make the first one last longer. This will also allow our ears to relax and prepare for the next time the cool part comes in again!

Thought this was pretty good ambience. Kinda reminds me of Ecco The Dolphin

Best sound for me. Best vibe and timbres. But Jofes is right. First minute (0:00 - 1:30) just awesome. Next part cant develop melodic ideas and stuck. But its almost ideal in other things. Really love it.
