"National Geographic needed illustrations to accompany infographics for a story about animal trafficking, but the art director, David Whitmore, wanted something a little more evocative and artistic than a typical infographic illustration. He had seen some loose animal drawings I had done on my blog and thought they'd be a good match. This job was unusual because instead of following the typical 'sketch' to 'final' process, I would simply do three to eight 'final' drawings, all very different, and have David choose the one he liked best. A very different way of working that encouraged lively, spontaneous drawing."
