Here are some pictures of a commission I have been working on this year for postgraduate Rosa Martens from the Netherlands. Rosa's thesis, titled
'What counts? Cognitive Development and Arithmetical Performance. The Role of Child- and Environment-Related Factors' is published by Neuropsych Publishers. I hugely enjoyed working on this project and the challenge of coming up with illustrations for such a complex subject, especially since it deals with issues relating to childhood. The commission included a cover illustration and 7 chapter illustrations.
