Reframing the question of style.
I was a writer long before I was an illustrator, so I always think of style in terms of "voice". I think voice or style are really an artist's point of view, an expression of individual experiences, training, and happy accidents (as Bob Ross would say).
I think the key to finding work is not trying to match your style to what you think the market demands, but building a portfolio that showcases your voice to attract the kinds of editors, art directors, etc. that are attracted to your point of view.
