Wonder

The narrator in Wonder actually finds it a bit boring how the Great Artist designed humans. "I" thinks "I" can do better, because "I" is also an artist.
So "I" gets to work.

Humans become increasingly wonderful, colorful, exciting... until the artworks take over themselves and everything becomes more and more bizarre. "I" cries for help and the Great Artist intervenes. His design is and remains a masterpiece.
... but the little artist remains a bit headstrong.

After two years, Mark Janssen finally returns with his own picture book. Once again, he manages to innovate and surprise his readers.

Wonder is a wonder.
