Artofeel first popularized this song here in 2009 with his Drove Through Flower-Girl to Get Paradise video, but I think it's been long enough that other videos made with it will no longer be critiqued under that vast shadow. I've wanted to make an AMV with this song ever since I had it in an Iron Chef competition several years ago, and I think Attack on Titan suits it nicely. However, I didn't expect this video to take over a year to make, even accounting for not having much free time to begin with. I truly gave it my all to make it the best it could be and I couldn't be prouder of it.
Subtle internal sync was my fav.
