at 3:50 there is a bit too much high end, but the track and the idea is sooooooooo great

It's a little too quiet at the beginning but then it picks up. The drums work together well with the vocal parts but we could cut the time in half if you cut down the quiet parts because it's pretty much nothing at the beginning and end.

Great song! I love this! It's extremely calm and unique! My only little nitpick (which is preference at this point) is that the drop takes quite a while to get to and lasts a short amount of time, but then again that's just me.
4:15 to 5:40 is the highlight for me.
