>>51439735My folder for all anime arts is a huge mess of thirty nine thousand pictures consisting of Danbooru, Pixiv, Twitter and even some Deviantart filenames, barely divided by the series they belong to and not counting reaction pictures. The idea of doing any attempts to re-sort them scares me, I can't even imagine trying to rename all of those.
The biggest regret I have about this structure is not making a series folder for Hololive early enough, because at this point I can't begin to hope to fish them all out of the "general anime-style art" folder.
