Hello!
As for the editing it was quite good, even really nice, but I thought it was a pity that you didn't mix your parts more. It felt like two different amvs put one next to the other to me.
Subjectively I liked the HxH part better because of the newer scenes, honestly I can't really watch anything about katanagatari anymore xD But I also thought the impacts were handled better.
Anyways, it's still a solid entry, good luck!
