Hey!
I didn't really like it, I think you had a nice flow overall, the scene selection was, more often than not, good but what threw me off were the colors and the overlay in the beginning. It seemed like you had no idea how to manage the post-editing part and you just threw a purple correction to make everything look more or less homogeneous. It's too strong and obvious to look good.
The overlay is even worse, it's been overused before in AMVs and usually not in good ones and yet you chose to spam it on a very long part for no reason.
As for the scene selection, some clips felt a bit too random, like the FMA ones, overall it was fine but I still think it lacked a bit of consistency in the second part after the Re:Zero bridge. Speaking of which, it didn't fit in a various, it's fine to have some sort of recurrent characters but here we got a completely random one-anime part and not a very synchronized one tbh. This part could have had much more impact.
So yeah, despite having some very cool moments (I particularly enjoyed the mirror scenes for example), I think it didn't deliver all the potential and the good things got a bit hidden by the color approximation. Still a pretty decent video, good job anyways o/
