Definitely a cool song sir. Given that you called it "experimental ambient" I can't really say that there's anything this song needs or doesn't need. There are a few things I would have done differently but those are subjective opinions that don't really help you out. Since your pointing out that bit about the bpm, I honestly would have gone a little slower. I might even have automated some tempo shifts to achieve some rubato. Other than that, this track is nice and chill. Beautiful :)
