Thanks Carey, for the idea to clarify the light source. I replaced the shadows at Edes left side into light reflections and added also some highlights on the body. I think this improved the image, what do you think?
About the book, I have to say, it has a strong political touch. I haven't noticed that when we have read this book in school. But now I read it with different eyes. You should know, it was written in the early 30ies in Germany from the perspective of the labour movement. What I love about it is the background story, the friendship between these very different kids and how open they are for the life of the other. Maybe one can think about extracting this story out of it and leaving the agitating out...
