That was interesting, you definitely knew what you were doing with your pace and scene selection all along. The build up is oppressing and you start stepping up the FX game when really needed. I would say however that despite having a really good fit between the song and the atmosphere you set up, the anime could have been more adapted, the simple editing in the first part could have had a few more tweaks in colors or some more slow stuff/overlays going on above the "static" scenes to reinforce the creepy feeling building on.
Also, I don't think there's much of a conclusion to the video, we understand his feelings and all but nothing really happens, it isn't bad per se but it feels like the story had something more to tell at the end. It's maybe more of a personal opinion here, though.
Solid job, good luck in the ranking!
