Melling has illustrated over 60 books, and written and illustrated around 15 of them. He became a freelance illustrator in 1986 and illustrated his first book in 1993. Working in animation showed him how pictures could move, not just on screen, but also on paper, and he realised that this was what he wanted to do when he started drawing picture books. His style of drawing incorporates a great deal of movement in every illustration.
Melling has been shortlisted for the Kate Greenaway Medal, the Smarties Book Award and the Independent Booksellers Award.
He lives in Abingdon, Oxfordshire.
