I do really like the atmosphere and idea of this track. and I even like the drums!
My main concern are the basses and the root note of this track: the 808 bass is a bit out of tune and, personally, I would have gone with more tonal growls. And you can really notice that in the end, the root note kinda changes. Also, in 1:30 or so, these growls seem nice, but they start burying the entire track, because they are quite "in your face" - like. I think they would fit much better if you use them as a background purpose.
To minor details: A little bit of EQing and reverb to the hihats wouldn't hurt
1:53, at first I thought that this pad was very out of tune, but I think that this still fits quite nicely I would have cut the highs on it though and I would have ended this pad at 2:03, so that it doesn't distract that much from the rest of the track.
Overall, there is still room for improvement, but what is important is that you could put your idea into realization. Now you only have to keep practicing and learn from others! Good Luck!
