I thought that could interest you to know which characters are the most likely to appear in the future :>
Why are all the ponies in the "Not interested" category? It's not because I don't like them. In fact, I really do like them and wouldn’t mind doing more about them. However, I increasingly feel that everything has already been said about them, at least regarding the main characters. To achieve something new, I would have to focus on background characters or explore extreme fetishes, which isn't the kind of storytelling I enjoy. It feels harder and harder for me to find fresh stories to tell about them.
Also, my main SFW comic is about them, so I guess I don't want to risk burning out.
