It's a little repetitive as some others mentioned. Funny enough, sticking with a longer drone can make it sound less repetitive if you keep changing the elements.

Hey Thomas! Very cool. I like it. I love the slow subtle yet peaceful vibe you got out of this. Solid work you have here. The piano adds just enough to give it that sparkle. I like it! 

It's a good submission. 

The repetitive nature makes the low volume kind of weird to navigate, I have to turn my PC volume up to 60 to hear this well which makes it feel like a lot to listen in.

Very simple, soothing track, very easy listen, a little bit repetitive but for ambiance it works well. Main issue here it is very very quiet you can boost almost +20 db and it would sound fine and not too loud, you have a massive amount of headroom to play with. Good job on the arrangement :) !

This one really got to me. A beautiful minimalist piece: not many elements, but every single one feels deliberate and perfectly placed. The atmosphere is genuinely captivating. Congrats, this is an excellent work!

This is a simple yet a really efective ambient soundtrack. I can picture this music in a game as it is.
Great work. 

Very Ambient, very Simplistic. Also sounds like Deathdream, which is one of my favorite Genres of Music. Very well done!

Very minimalist, I think it's fitting for the ambient theme. Loved the reverb on the piano, filled up a lot of space for such a light handed mix.
