Short, but wonderfully sweet. The production is excellent, the timbre of the strings and brass is marvellous. The others pretty much covered all the awesomeness of it.
Some things I reflected over:
I would've kind of liked a slightly more fluid melody - the note-against-note chorale style gets somewhat old with time.
Some light percussion, cymbals perhaps, would've been neat but it does stand on its own as it is.
The harmonic palette used is great, but when listening pointedly to the arrangement, I really found myself wanting more contrary motion (though 0:42-0:43 is great!) in certain places.
Disregarding all that crap, this is the best I've heard on NG in a long, long while.
