They're just short comedic things- as long as the writer can come up with scenarios to put the characters in and know the jist of their personalities, it's good.
If the writer(s) like the characters and want to continue working with me, I'd be glad to take them on. If they don't find the characters interesting or feel comfortable writing someone else's characters, they don't have to continue on the project. This could work as good practice for those who want to work on professional projects. I also have a Patreon and merch on Redbubble. I'll split any potential profits from the comic with my collaborator(s).
