Jemima Khan's article about trichotillomania in todays The Sunday Times Magazine http://www.timesonline.co.uk/tol/life_and_style/health/article5760104.ece reminded me that a while ago I created two illustration for an article in a Polish psychology magazine Charaktery where I learn about this condition for the first time.
I have to try more to combine photography with drawing - it is not my signature style in illustration but in this case I think it was very effective as they used both illustrations on a spread page layout.
