Beginning work on my graphic novel project

Right now I'm doing my first bit of actually productive work on figuring out the plot for my graphic novel assignment. I always have trouble when I try to start a project without already have an idea for it, as opposed to starting the project because I was struck by an idea. But I think I've got at least the seedling of a plotline. Ages ago, I wrote a ten minute play set in the same universe as To Think of Nothing, about the first actress to play the role of Selene in Cassander's play being afraid that she's not good enough for the role, and not good enough for her acclaimed director, who she regards with a kind of reverence that might hint at something more. I like the bones of that play, but it should really be rewritten now that I've grown as a writer. I want to adapt the idea of this piece for the comic, because I click with the concept at least enough to begin, though I am still deciding how much I want to stick to it or deviate from it.

I go often to using theater as my subject matter, because I know and love it well. I can get engaged and write intelligently about the process of making theater. As of this writing, my two one acts that have been performed use theater as subject matter, To Think of Nothing and Merely Players. From there, To Think of Nothing spawned Fountain Thoughts, and that little piece I wrote to practice iambic pentameter. Eventually I'd like to write other things in that universe. Then there's Merely Players, from which I am in the practice of adapting the larp Break a Leg. There's also Just So, which lovingly mocks the kind of people that are sometimes drawn to theater. I hope to not overuse it, but when I'm having trouble figuring out what to work on it's a good shortcut to getting myself invested in the material.

The question now is whether to follow the thread as it appears in Fountain Thoughts or to just use it as a jumping-off point. I know I want a major concept in the piece to be a rivalry between two female artists, played by niobien* and blendedchaitea*. But a scene I worked on today that I am really feeling makes the most sense if Rachel's character, at least, is a dancer. Now, I could make it so they are both dancers and actresses-- certainly a thing that happens --but perhaps just to move myself away from my typical milieu I should make this a story about dance rather than theater. I'm even lucky in that my two first choice models are talented dancers. But if I did that, I'd be concerned that my lesser familiarity and understanding of that process would make me less able to depict an interested story within it. I guess I'll have to work on the plot a little more to figure out which setting would support it better. I just know I really like the one scene I did today, and that at least requires dance.
