I liked the atmosphere of this piece quite a lot, and the light piano was a nice touch!
My critiques for this would be:
1) I'd like to have heard a little variation in the bass - having that repetition is nice to create the vibe, but I think having even a slight change once the piano line on Track 4 comes in would have been a cool contrast in sections without being too different.
2) I would've probably liked to have heard a bit more reverb on Track 2 and not as strong of an attack. I like the timbre of the part and how it seems to change in texture over the course of the piece (maybe?), but I think if you played around with its velocity a little bit it would help it blend better with the rest of the tracks, imo.
Thanks for sharing this - keep up the good work :)
