Pretty great track! I really like this soothing atmosphere, even though I'm not a big fan of ambient music! I don't really like the impacts at about 7:08 - 7:20. I think it would be worth putting a lowpass on them, and it is also worth turning down their volume, I think they spoil the atmosphere a little. I also don't really like the end, it doesn't really fit into the track itself. I would also clean the rather strange parts like 5:09 - 6:14 as they are a bit annoying. But mostly not bad! Good luck with your development! :)
