On behalf of everyone on this god damned forum, it practically died a while ago due to people being busy and lack of colors and fun on this website *flips tables*. That's why I have personally been slow at commenting on this. My bad. OTL
As for the video, I can't... I just can't judge it in an objective way: I was strongly disappointed by Aku no Hana when it came out because I was expecting art like that of the manga. So that's a huge turn off for me.
However, I find that the story made sense through the AMV, and the editing was well fit with that kind of song. Not my cup of tea but ah well.
Technically speaking, you have some split-second frames here and there that should be fixed to make it look cleaner. But I like the simplicity of it, keep up the good work. ;3
