In its current state, the song is enjoyable; there's a weird sense of relaxation and smooth energy that emerges from it that I love; it's both inspiring and dance-capable. But I think the main issue is in the song's duration. it's just too long, and with little to no progression, it ends up being super repetitive.
The song is structured perfectly, and the opportunity to build upon the already laid down foundation is ripe. I think if you did a new composition for the second half with the same kind of style, along with a much more sustained ending that's satisfying, I think this tune would be droplets away from reaching its full potential.
The best way to utilize the song I feel is either in a mix, or as a background tune; the atmosphere is what ultimately sells it. It's a phenomenal effort that suffers from the lack of diverse elements within it. It's far from bad; just a little bit of revision could really do it justice.
Great work, although there's no doubt that you've improved your skills as a producer since!
