I didn't really like this one. First of all I think the 21:9 aspect ratio didn't match the mood at all. The scene selection was especially random and it was hard to stay focused with so many different animes that didn't fit well together.
The audio cuts are very disturbing and the voice overs were kinda pointless.
Finally the masks are really ugly, if you don't have time to mask correctly, I think it's better not to do them at all and rely on simpler techniques. By the way, the twitch at the beginning which are the same, regardless of the scene on which it's used, weren't really good because of the obvious repetition.
I see that you must have put a lot of effort in it and I may have come out a bit agressive by just stating what I thought, I'm sorry I'm commenting a lot of videos today xD I'm sure you can do a cleaner edit, keep it up!!
