There are parts of the story, where she pushes back against the illustrator, who responds with new drawings which she also rejects, and so forth and so on, that can only be written after I see what the illustrator does.
Another big challenge for this story will be how to portray the main character breaking out of the story to talk to the author and illustrator. Should she just speak from where she is within the currently illustrated scene? Should there be some kind of artistic effect that signals her asides? I have no idea. But my illustrator will!
Here's the first time my main character speaks to her author and illustrator:
Whoa! Whoa! Whoa! What kind of story is this? Can’t you think of a more interesting place to send me than the Moon? And I want a dangerous mission. An exciting mission! And what’s this “spacegirl” nonsense? I bet if I was a boy, you wouldn’t be calling me “Spaceboy Billy”!
And you, Mr. Illustrator! Is this the best you can do? I’ve got fancier coats in my closet!
