I first heard of Australian author illustrator Chris McKimmie on Children’s Books with Kate De Goldi.
One of the secrets to success as an illustrator is having an instantly recognisable, one-of-a-kind style. McKimmie’s various book covers will give you a glimpse of his style.
The naive style of art also works really well to encourage children in their own illustration. The Dog Man series by Dav Pilkey, and the treehouse books by Andy Griffiths and Terry Denton do the same thing. Kids look at these pictures and think, you know what? I can do that. It doesn’t have to be realistic. Realistic art is sometimes confused for ‘good’ art.
Art is ‘good’ when it makes its audience feel something. That’s the only criterion. In picture books, art also tells a story.
