I do agree this is your best work so far that I've come across, but I am noticing the same sorts of problems. (This sounds more like a Rune Forest than the last track btw.) I will say try to incorporate more melodies, counter melodies, etc. Perhaps you're just going for an ambient sound here. You'd still want to introduce things that don't make the listener bored.

Getting feelings of nostalgia, calm, and melancholy. I like this track a lot, the melody lead sometimes changes in a jarring way, and it adds a slight uneasy feeling which is good if that's what you were going for.

Can't really think of too much to say as the track is pretty simple which is good for ambiance.
