A friend and I have made a discord group for creators to do character collabs in different themes.
The current one we are planning to do has the F.r.i.e.n.d.s tv show theme. We are already around 11 creators who are going to take part of it, but we are planning to do it in groups, so everyone can get included as each illustration collab is max 6 characters. If you don't like F.r.i.e.n.d.s, but want to join the group then you are still more than welcome. There will be plenty of collabs and everyone can suggest and start one at any time.
If interested please comment below or DM me with your link to your comic and your discord.
I'll invite you to the group through discord.
Edit: your character doesn't have to be human to join in! : D
