It might help to think of the Hollywood model. The pretty young men they put out front are the actors and you are the writer. It's been noted before many times that writers don't get much respect, but they are the geniuses who come up with the narrative, the dialog, and the ideas that make up a successful production. Writers usually don't show off well to investors or at parties. That's where the pretty faces come in. I'm usually dismissive of the next young genius on the cover, because I'm more interested in the real brains behind the outfit, who may or may not be marginally social-able introvert living in an eco-bunker somewhere who definitely does not want the attention.
