I liked how you tried to come up with something new for the effect concept (the blured edges and especially the whole transitions you did with it). However, the inverts and the piano keys pretty much destroyed that whole build up for me. Those kind of effects almost kill everything every time whenever someone uses them.
Also Gravitation has a somewhat solid storyline, and it feels weird to just set the scenes out of context in this anime (I dunno but for me it felt kind of wrong to just see the scenes completely random jumping from one part of the story to a completely different one).
I thought that it was nice that you didn't use most of the overused Gravitation footage since there already are so many Gravitation videos (still I haven't even seen one video that focuses on Yuki's past for example :p). I say the series needs a damn second season or something so we editors don't always have to use the same scenes.
As for the beat synch I think it was ok, even though I also think that there could've been a bit more hard cuts it didn't really bother me.
That's all, pretty decent video overall
