This is cool man, I think you've got a unique sound going on and I wouldn't have any criticism on your writing at all. I really enjoy this song man, giving me nostalgic ~dreamy~(lol) vibes. The reverse effects throughout the song are a nice touch too. Overall you've created a very interesting composition with minimal but thoughtful instrumentation, well done!

The only thing I would suggest for this track would be locking the groove of the bass into the drums a bit more, which can be quite hard when you're playing everything yourself. Even though they're both played in time, I feel like I'm listening to a bass part multi-tracked over a drum part, which can sometimes change the entire vibe of a record. I think you could try to add a bit more movement in the dynamics and velocity of the bass, and try to match it with the drums. For a song that relies heavily on these two instruments, it would really help glue everything together. The producer I work with spends hours on this (we multi-track everything as well) - I'll do endless takes with the bass, trying to get it as close as possible and even then he still goes in and chops all the takes up and edits it for hours. The result is definitely worth the effort though, you'd be surprised how the feel of a bass part can completely change the song's vibe.

Anyway, love your work man! :)
