Mr. Ratzinger...I recorded the various stages of the process of this illustration, which can be seen below.

This is how the illustration eventually turned out. I think it captiures the atmosphere and fantasy feel of the story.
The previous sketch for the Peter Pan book cover was rejected. I agree with the publishers comment that that design was too much about Captain Hook, and not as much about Peter Pan. These new concept sketches for the cover were approved. Let's paint!
A new edition of J.M. Barrie's Peter Pan will be published by Ploegsma publishers. These are two sketches for the cover illustration...

I drew these sketches of my son while he was playing. He was moving all the time and not standing still to pose for me at all. When doing sketches such as these the main goal is to capture the essence of a pose in just a few lines. No rendering. It is a very good exercise for the eye.
This is my contribution to the project 140 hits in art : a book in which 140 artists illustrate their favourite song.
