Schoolbook illustration has been a major part of my workflow since 2003. For German schoolbook publishers I draw illustrations for Learning English for all school types. This includes works both for children who need extra support and those who need extra challenges.  Sometimes it's an advantage to have a native familiarity with British and other English speaking cultures. Adventure books and stories for young people are my special favourites. Nevertheless, I take care when creating even a simple bar chart that this is not just clear, but that it is also visually pleasing to the eye.
