I don't know of any, but then again... I don't usually go actively seeking out groups per se. That aside, you could always start one of your own?

I'm not opposed to an artist's place to bounce ideas around and the like.

Sorry, I Am Not A Artist, But I Am Open To Collab However, I Lost My Discord By A Hacker

I may know discord server like that

I am in a Signal after dark chat.

There are small and mid size servers for local furry communities (germany), may there is something similiar at your place? Once I was on a bigger server and do not recommend it. Too much posts, people will not notice you without spamming.

What about opening your own server and inviting your buddys and fans? A friend of mine did that and now its a growing community.

I know of a general furry community that has a lot of artists already in it over on Discord. But I don't know of any off the top of my head that are solely dedicated to artists and artists only. That said, they do have a good variety! Modeling, writing, drawing, etc. Although the favored content can definitely be offputting at times.

I think Darius knows of a few such groups?
