One of the events in the conference was an illustrator's intensive where we were given an assignment to illustrate a specific sentence in the Pied Piper story. We were instructed to submit sketches to Kristine Brogno, the art director at Chronicle Books, to which she offered feedback. Then, based on her feedback, we created final art pieces which were presented at the conference.
This was my sketch:
The feedback included varying the ages of the children more, as well as the expressions on the adults. Overall, she liked the movement of the piece from left to right, and the environment.
Here's the final:
Other comments from illustrators were to change the red-headed boy's striped shirt because it was too similar to the piper's, reposition the little girl in front to de-emphasize her as the focal point, and to clarify the vignette of the man standing in the window above the piper.
After finishing the Pied Piper piece, I liked the colors and the feel of the piece so much that I wanted to do more. So in the week before the conference, I worked up another illustration from the story where rats are taking over the city because who wouldn't want to paint a plethora of rats?
