Authors hiring artists want the artist to share their vision or bring a fresh interpretation to their story. You should love the lines and colors the artist uses! Can s/he tell a story with an image? Is the art lively or static?
In children's books, the child should be captivated by the images, whether beautiful or quirky or humorous, so s/he remembers the words of the story... When images evoke the memory of the story and the child learns to read.
My price for illustrating depends upon the nature and scope of the work, the involvement of participants, and the lead time on the project. I would love to talk to you about your project. Contact me to start a dialogue.
