So, yeah. I just feel I'm having trouble building a series I feel satisfied with. Mostly with selecting characters I want to represent my series. I have some story ideas in my head, but I just don't know what characters I want to add. If I just add completely random characters, I have trouble feeling invested in the storyline. But I still want to make the roster unique. any suggestions?
