Good elements. Needs a little more mixing. Metallic part of the percussion that starts at 0:19 and continues till 1:25 is very loud in the mix. Your clap starting at 0:28 through 0:47 is also loud. Like, you'd expect a very forward clap like that in a high energy genre but not atmospheric ambient like this. When you bring the clap back in at 2:05, it's not a problem because it's better balanced with the tune do to there being more volume in general at that part of the tune, so it blends better.
Nice ambient effect at 1:55. I like the delayed arp sound you have that starts at 0:29 and appears again in other parts of the tune. The percussion at 1:29 through 1:45 is very nice. Good satisfying sound on that one. The glass clink sounds added to it at 1:45 are loud. very nice pads/melody at 2:30. I like how this piece evolves. That linear through form evolution is very important to keeping things interesting, particularly in atmospheric music genres. Round 2:33 through 3:02 you bring in some sort of buzzy lead playing an ascending arp line. I think a different type of synth patch would be better suited. The one you used, kinda sounds like it belongs in a house mix.
I see you are using that tongue drum sound. This is a great application for it. It gives some warmth and beauty to balance out what is a pretty melancholy piece of music.
One last rather insignificant thing. Don't leave your tune's thumb blank. It just looks so much better when it's filled with something eye catching. Also a blank thumb makes it look less professional.
