The intro is a little jarring, maybe add one bar of piano at the very beginning?
I would also save the strings for later.
Piano sounds too loud to me, and I'm a huge fan of Noire.

Also agree with CD, the augmented chord is out of place. I wouldn't call it "augmented", because the 5th is not being raised; if the root was an Ab you would be correct, but it's an F minor chord with a major seventh, not an Ab aug chord. If you want to keep that harmonic tension, I suggest only playing the E natural for one beat instead of four, use it as a leading tone to F. A full measure of that tension (to me) removes some of the intimacy of the song.
The short string swells sound unnatural to me, and I would put the strings further back in the mix.
I think a longer pause at 2:07 would have more emotional impact.
The high pitch (bell?) at the end is a little shrill, I suggest dropping it way down in the mix, (and I say this as someone who's hearing above 10k is almost non-existent.

Overall I think this is a wonderful piece of writing, but not yet ready for the aforementioned high bar for vocals in the sync business. I think this could be an excellent song for stage use, it sounds very broadway Andrew Lloyd Webber, and the vocal delivery reminds me a little bit of "All I Ask Of You."
