My friend and I created a Discord server specifically for sharing and creating original characters! A huge part of comic making is of course the characters, so I thought I'd share here in case you're interested in joining.
We have a lot of channels specific to sharing information, writing and art of your characters, and we also have channels in which we share tutorials and critique each other's art/writing. We're also completely open to you self promoting your comics and other work!
Click here to join the server!
(I'm not 100% sure if promoting servers is allowed here but if it's not, feel free to take this down.)
