If everything was as good as your voice this would be perfect :D
[Ignorable nitpick coming up]: What kinda broke my immersion for a second is the breathy clicks on the organ in the beginning and the computer perfect timing on some of the real-sounding instruments.
Composition, flow and attention to detail very good overall. Harmonies just yasss. Also cannot help but love people who utilize good dynamics instead of just going "compressors yay!"
Keep it up :D
