There was definitely horror/psyche potential for HxH and I can see why you chose it. I do believe the scene selection was a bit weaker than it could have been in this aspect though. It still felt very much like a typical HxH scene selection except for some very particular scenes.
On the technical part, I think the red CC was handled a bit poorly, when the skins are going green-ish you know the color change didn't work well.
The editing in itself was a bit inconsistent with some weird push transitions and a slower pace the more we progressed in the video, it seemed you had to rush a bit more and it's a pity.
Good association nevertheless, good luck o/
