Well, that was enjoyable besides the background noise that's always there.
I think you could use some structuring in your songs.
Just to experiment try a few cookie cutter songs. (Intro, Verse, Chorus, Verse, Chorus, Peak, Verse Chorus, outro chord) Then a more complex pattern could include bridges, or playing half the chorus the first time, a pre-chorus that also surprisingly leads into a breakdown or slowdown.
It just sounds a little like disorganized jamming to me. You tried to do some reverse which is an acceptable technique but, idk it wasn't right considering how empty it felt. (add reverb to reverse elements, fills up the space)
I suggest you listen to Agalloch. Now, they differ from you in that they have a drumkit and powerchord metal guitars, and a singer that occasionally tries to impersonate
a demon.
But they also stretch stuff out and still sound good and have these ambient vocals like you do, and have this forest acoustic guitar sound to them. Listen to "Not Unlike The Waves" and maybe you'll find some other stuff by them you'll like and learn from. And up your sound quality dude, seriously. Lo Fi?
I did enjoy listening to this while studying, it was nice and calm.
