In book illustration, there are two main directions: one is illustration as decoration, explanation, and interpretation for, in the broadest sense, literary works, and the other is informative illustration for scientific or purely factual texts in reference books.
I enjoy and have experience in both directions. I create illustrations for books for adults, children, or educational purposes. Feel free to share your idea, concept, or story with me. Give your novel or reference book more depth. I’d be happy to advise you on the diverse illustration possibilities for your book project.
