This illustration was for a book about Zoe and her sister Lilly. Zoe likes to play superhero and her helper. Her helper was of course her little sister Lilly. Lots of squabbling followed. In this story, they are Superhero mermaids and are saving the oceans. The book is full of make believe play and endless craft projects as they first paint their ocean and then make all the sea animals before diving into it in their super sub.
Saving the oceans is a recurring theme in many of my books. The polluting of the oceans and our future lack of oxygen is of great concern to me.
