The mentioned twitter account matches an artist with a danbooru entry, but I don't know if it's actually the same person since all their tweets have been deleted.
No idea who the cosplayers are on a lot of these. Only a few have @s mentioned, fewer of those are still live accounts. im making entries for everything that mentions a live account (this one does have replies from an account, its just private and i didnt notice its there, and i can't be sure it's one of the cosplayers in the image from the context)
