Children's Book Illustration. You finally finished that children's book you always wanted to write and now you want to add illustrations to enhance the story. We at Iskon Design believe that the best way to come up with the most stunning illustrations is to communicate with the author throughout the entire process. After we review the manuscript and talk to you about your book, style and number of illustrations, we will send you initial sketches for your review. Visit our portfolio for a sample of our work.
