Really nice mixing right out of the gate on that first instrument. Nice texture, right amount of reverb, nice delay. Most of your instruments sound nice by themselves, you seem extra good at choosing reverb.
I like the beat too. But I would say overall, fill up the track a bit with more layers so that the writing of the song makes it a bit more unified. It sounds like you've spent a lot of time trying to get your mixing and effects to sound good, but not as much time on the composition of the song.
I'd even experiment with taking this same set of instruments and effects, and trying to write a less experimental song with it to see what comes out.
Forgive me though, the song is not BAD, I just think it's lean. The solo instruments sound lonely to me. Around 2:40 you start to do a bit of a rhythm with the piano and for the brief time that that is happening, it sounds a bit more filled, try to go for that throughout the whole track and you'll have a really cool project.
I like the overall feel of the elements of the track and it's personality, good stuff and keep up :)
