Here is my interview with Walter Rhein.
The act of character creation is different for every artist/author by definition. I abhore authors or editors (hell, anyone) that try to dictate the way in which someone is creative. Instead, I believe that everyone has to develop their own creative process. Often times those methods are a patchwork of activities and actions similar (or even identical) to what another author’s and probably more often, they are a developed through an author’s own experiences and efforts. Everyone does things differently, and my method for thumb nailing characters is probably far different from most others.
