Hi! This depends on whether we have creators who are willing to draw/write canon + OCs. For art, please upload a reference image for the artist (e.g. you can make your OC in Picrew and Gacha club, or other photo/image references if you have them). For fics, you would have to provide a detailed description and any relevant info about your OC. In the event that no creator is available who can fill your prompt, do have a backup prompt ready just in case.
