Author Cheryl Block, wrote an children's educational book on spiders. One of the primary parameters given was to create anatomically correct but also friendly spiders.

GTD created a spider characterization, which followed the author's suggestion, that the spiders needed a friendly face. This, coupled with a style of spider "body language" which would be identifiable by children as approachable, to express the flow of the story and learning.

Also the anthropomorphic thinking and emotions of the spiders were key elements in creating each illustration. This was essential in communicating the author's intent and information.
