Drats - I was 10 minutes into a comment when the page crashed.
Lovely voice that is Judy Collins or Judith Sill like.
Lovely song.
The almost mono mix stacks up a lot of bass from the guitar, bass & bass drum in the middle of the image and they blur into each other.
Double tracking and hard panning L - R the acoustic, or using an ADT plug, until the mandolin comes in to then balance against just one guitar would open things up. Pulling the 2nd vocal 20 points or so away from the main would lessen the trampling it does - it also needs a high pass on it.
ALL of the components are great and a proper mono mix would be fabulous as well but it would take some serious EQ carving etc to sit everything on top of each other.
You've done terrific work writing & performing but the mix doesn't do it justice according to my ears.
I'm probably entirely wrong & my tinnitus is stepping on everything so please ignore me if I'm not even slightly right.

Cheers
