I like all the characters we have so far, and wouldn't change a thing about them.*
Some new female characters would be great, though. Mrs. Slitherss, that exotic beauty whose personality and visage make Aphrodite say "screw it" and pack up her bags, stands as an example of how great a female character can be in this wacky hybrid of an oil spill, a fever dream, and a legitimate fantasy universe you've published for us.
Please consider it. You could even try to make them as sophisticated, erotic, and beautiful as Mrs. Slitherss, but that's a tall order so don't worry too much about it.
