Boosting the kick and the bass for the choruses is very weird for me. I prefer the overall leveling in the softer parts (around 1 minute mark to be exact). Excluding that, the mix is solid. The composition is good enough to do its job. Doesn't really grow on me tbh, but Ambient stuff isn't about catchy melodies, most of the time.
Since my points are rather subjective, I'm not gonna take any score away.
