I'm really impressed with the calming atmosphere you have created here! I love this style of more ambient and repetition based music, and your concepts really remind me of an artist I've heard called the field who focuses a lot of their music on looping specific looping patterns. I think the initial concepts and loops you've chosen to base your songs on, and I think a way you could develop on that even more is by being more purposeful on how you choose to develop your ideas. I feel like sometimes the way you add in more layers can sometimes become a bit too dense (notably in the later two songs), and it can be a bit hard to parse out individual elements. If you want to create a more dense texture, I feel like dropping out some elements will help make sure that it can be dense without being overwhelming (eg, some of the rhythmic piano parts you have).
Another thing I think would help out a bit is smoothening the transitions you have between elements, especially in the first two songs but I also noticed it in convergence around 1:10. In songs like this I find incorporating new elements is most effective when there is some sort of push leading you to prepare for less subtle changes, even if you are planning to drop in volume from a louder section, you could even build up in volume so that the sudden drop has more weight. While this can definately be difficult to nail if you are structuring the song as a piece that would build throughout a level, I think Lena Raine does a fantastic job at illustrating ways to do this in Farewell. Overall, I did enjoy my listen through and I hope this feedback is somewhat helpful, as I really love this kind of music! Good work, and I would love to hear more of what you do in the future.
