I get depressed when the sun is clouded over. It affects me.
A lot of illustrators have one central character and then they develop it, and all their books are based around it. But that was not my wish. I wanted to introduce children to the whole creative side of many aspects of life.
I've never been invited to do an exhibition or do a talk in England, except once, about 10 years ago. I've given talks all across Canada, many in the United States, South Africa, Singapore, Hong Kong, Japan - but not England.
In England, there is a dividing line between artists and illustrators, who are thought inferior to painters. Well, that's absolute rubbish. Some of the most creative work is being done in children's books. In Japan, everything is art. They don't say painting is better than ceramics or dress design.
