Wow. That was just... the sentiment you captured was just *perfect*. I know it's been said before, but that really was bang-on canon for Stuart/Vince from Stuart's pov. The more vulnerable, sensitive side of Stuart is so over-looked, even in the fanfic I've read; but you've... you just *got* it, and more than that you've captured it in this vid for everyone to see.
You've done what every 'involved' fan should be (nearly) always aiming to do, which is to be true to canon not only in the characters and the themes, but in the way the themes are in the show. It's too easy if you're writing or vidding angst to take it too far, to forget that these characters are thirty (or thirty minus a few months) and treat them like teenagers, but your combination of editing and choice of song got the angst at exactly the right level. And I think the credits worked really well, with the fading-to-blue.
