"I’m not free to do whatever I like stylistically, since my work is going to be wedded to the words. The responsibility is to help to tell the story, without interfering with the readers’ imagination. In a way it is a bit more akin to a sets designer or to providing music for a film. You are serving the text and you are serving the story. So that’s what I do. I’m an illustrator. But I think you have to be an artist to be able to do that as effectively I can."
