Just hearing it on this computer, it sounds like the voice is a few dB too loud for the music. I'd back it down and let it set in the musical bed a bit more.
harmonies are sweet.
one thing's for sure..... BiaB certainly excels at BG music. Fiddle sounded really nice.
good modulation.... you tripled up on the harmonies in the modulation.... back one of them down a bit so it doesn't run interference in the form of comb filtering.
All in all,,,,, this is a really good job.
