An ActivityPub-federated alternative to DeviantArt/ArtStation would be nice especially if it will let you manage and update assets/sources attached to artworks.
It's great that the Fediverse features different implementations that resemble mainstream social networks (Mastodon/Twitter and PixelFed/Instagram) and this is why I would iterate for DeviantArt/ArtStation too (PixelFed looks too much like Instagram for this purpose)
@post I wonder if a https://pixelfed.org/ large instance might do the trick (for the 'portfolio' view).
