I enjoyed the track.
That autotuner could in my opinion be skipped (it's the one making that "digitalized" sound), but it was quite sparsely used so it was within reasonable limits for my taste. I think it gave the track a bit more "modern" sound. Why does the word "sci-fi" pop up in my mind as well?
I agree that it would have been easier to judge her real talent and voice without that effect, but she seems to have a nice voice. I liked those harmony parts as well.
There's some hit factor in this song. The current mix didn't do it for me though, it sounded a bit "flat" in some way. Not alive enough. Difficult to describe...
If there's something I missed in her voice it was power. She seems to sing quite softly all the time. More powerful passages would have been good for the dynamics, but I think that's something she'll develop better over time.
I'd continue working with her.
EDIT: Saw your post. I was almost sure there was an autotuner in use here.. If not, then... wow...
