Nice work. I liked the grainy and squiggly line effects you added. I didn't like the inclusion of text, though, but that just might be me being biased.
Since you used fan art at the end, I advise you to source all of it, so you don't look like a thief. Better yet, next time you want to use fan art in your videos, ask the artists for permission to use their work (if they're from pixiv, use google translate!). They'll get a lot more respect for you.
