In short, there's a pool for riyo's artworks - should there be one for official art too? I've noticed that there's a lot of official art not uploaded from FGO, and i was wondering wether someone should make things more ordered so people can upload unuploaded official art.
Although that would fall under official_art + fate/grand_order, there are a lot of Craft Essence artworks, so that way people can distinguish between Spirit Origin stages and other stuff.
