When people think girl adventurers, they tend to think of a spunky, plucky tom-boy with a chip on her shoulder. I'm not saying that this makes for a dull character, but I think other types of adventurous girls exist. It's easy to fall into well-established tropes, believing that the tropes of a genre define the genre itself.
I think about 'The Simpsons,' which has been going on for 25 years. Homer is still in his late 30's. Lisa is 8, Bart is 10. Their stories are told. Yet the series keeps going on and on like a zombie that won't lie down and die. That feels forced and unnatural. The characters never change, grow, age.
When I first starting conceiving series like 'Courtney,' 'Polly,' 'How Loathsome,' etc., I was shooting for closed story-arcs but open-ended concepts. Then I started realizing I was committing myself to potentially endless series.
Us comics guys tend to get really good at the things we draw a lot. I'm good at creepy old forests, Victorian houses, underground goblin cities, and beautiful but creepy fairies.
Artists forget than the first purpose of a comic character is to convey emotion. Everything else, like realism, or other kinds of virtuosity, is an optional extra. If you sacrifice expression for the sake of other concerns, you're putting the cart before the horse.
Basically, Urban Fantasy means D&D in New York. Ordinary people have no idea that they share the world with fantastic, supernatural creatures. It can't just be vampires or werewolves; it has to be a whole continuum of fantastic beings, with their own society within society.
The living werewolves have genuine needs and desires, which, though they may oppose ours, are valid. Even if they want to eat humans, you can't really call them evil, any more than mice can call cats evil, or chickens can call humans evil. It's all just a matter of where you're standing.
