Lovely melancholy... this is something I miss in most ambient released at the moment.
I really like the moment where it sort of breaks loose at 4.20 or so. It jusitifies the monotone start (thus monotone in a good way).
What I would like to hear in this tune is birds! Random digital effects wouldn't add anything in my opinion... this song needs real soundscapes - it needs to go outside the listeners "head" if that makes sense
I might also add that I didn't really like the sort of trancey effect that pops up ever now and then (for example in the start at 0.22 or so). I totally understand your intention with it, and the sound itself really fits, but it feels a bit malplacé I think. I would like it to be in a higher volume, and maybe increase the delay on it so it doesn't fade away too fast!
Anyway really nice track, I am a big fan of melancholy of this sort. Add some birds and I would be in love
