This is the third story to feature the Three Little Worms (it's the second to feature Bucky Bug) and I'm told there are more stories to come. I absolutely love illustrating these characters. You can read the full story and see the rest of the illustrations in the current issue of High Five Magazine (January 2010).
Here's a sample of the final sketches (p. 3 & 4) that were approved by Highlights High Five Magazine, along with the final art for the same images... enjoy.
In order to get the child-like look for Bucky's drawing I created a separate work of art using oil crayons on charcoal paper. I scanned the image and then warped it in Photoshop, according to the perspective of each scene. Take a look.
