Designing the boy character was also quite fun. One key element I kept in mind during the design process was the idea of contrast. The environment had lots of earthy tones - lots of greens and browns, with sweeping, organic lines (like the trees in the forest) and the hard edges of the island's mountains. Alternatively for the characters, I tried to use quite rounded shapes for the hero and his dog, and incorporate bright, bold colours and patterns so that they stood out. I put myself in the boy's shoes, and imagined how he would have felt as he travelled the island in search of Pirate Frank's treasure.
When Nosy Crow first approached me with the manuscript, I knew immediately after reading it that it was going to be a really fun book to illustrate, and boy was it fun! The Treasure of Pirate Frank was the last picture book Mal Peet penned before his passing in 2015, so it's been such a great honour illustrating this book for him.'
