I didn't like the original version because of the snare, but your final mix sounds good to me.

and I enjoyed the listen.
When Natalie sings for you, she always has a nice Karen Carpenter touch
My only criticism is that while I would classify the song in the "easy listening" genre, it's a bit too "easy" for me, as it doesn't have a distinct chorus (lyrically it does, but there's no dynamics or other variety).
