I love the subtle string work, it's never overpowering. That was the first thing that stood out to me.
Nothing is too busy, or trying to compete. Which is a very difficult thing to get right for me.
I also love the little piano inflections at 2:19.
I really dig this, stellar production too! Love the harmony work too.
My only critique is that I would have made the vocals a little fuller in post-production on the recording. Maybe layered them and panned or something, but just a bit more low end/beef to them to really bring the song right up!
Also, footnote, great idea having the little audioclip at the end, really unexpected.
