@dookie they're all from baraag.net, mostly loli artists. Pawoo.net too, but it's Japanese so it doesn't make it easy to find stuff. It also kinda glows. Mastodon.art has more "normal" art but don't expect them to be able to reply to you.
The other place I go for art though is Newgrounds, which doesn't allow loli at all, and there are a pretty good chunk of artists there.
Unfortunately there are way too many that are still stuck on Twitter.
