A sample illustration for a children’s book to make a selection for approximately 20 illustrations to match rhyming stanzas that tell the story

I need an illustrator for an older children’s book. It is about a Cheetah who thinks he has been made a knight after a confrontation with a real knight. He lets it go to his head. The “real King of beasts”the lion, gets word of his behavior and confronts the Cheetah. The lion senses the Cheetah’s remorse and makes him a “real knight”. The Cheetah mends his ways and behaves like a true knight and, of course there is a happy ending. I am looking for approximately 20 illustrations that are more “mature” than “cartoonish”. Please see illustrations from “The Ship’s Cat”. I don’t expect anything that detailed, but something more like that than like a cartoon. I’d like to see a sample of the illustrator’s interpretation of the stanza, and I’ll make my choice of illustrator from his/her submission.
