Hello!
It has quite a nice vibe, I enjoyed your scene selection except maybe some of the filler scenes you added that could have been etter integrated imo but I think that's mainly because your anime is really different visually. The little comps here and there are nice even if some masks are a little bit too easy to spot.
The fade cut to the song at the end is a bit rough but other than that, I didn't really feel your rushed it so that's good!
Good job!
