@jgilbert@mastodon.social the only thing i can think of right now is https://mastoart.social/about but I've never used their instance and I do not know much about their administration team. If you could specify what type of art (I know some instances that accept furry artists and that you'll get a lot of exposure there) I may be able to narrow it down or someone around me may have ideas. I'll boost the post anyway so you can get more visibility.
