First of all cool song. I guess from the posts that I just listened to the the reworked version???? Sounds good. I guess the only thing that stood out to me was that on my set up the backing vocal track/tracks seemed to stand out more than the main vocal track. I think that they should be set back into the mix a little bit more. When the secondary track echos the same lyrics I feel it should be less up front than the main vocal track. Other than that there are a few bright/harsh spots on the main voacals that I think may be able to be fixed with some eq.
Anyway. I think you did a great job and your wife too!
F.S.
