Very calming, sad little chords. I would place this in perhaps ambient.
I don't have a lot of critique as it's quite a simple atmospheric piece. I very much like the touches at 2:17 playing with noise. However it is quite a long time to have a lot of the same elements playing without much in the way of transitions or change. Perhaps some play with other noise samples, transition noises, and varying more so when different instruments come and go will help with that. I think you did the best you could all things considered.
Thanks for coming out to NGUAC!
