With the release of Treasure Island on the iPad I'm happy to show some development work from last year. I would work up the roughs on the Cintiq before moving to colour in Photoshop. Many ideas are discarded, but that's the nature of quick thumbnails. You hope to capture the energy of the doodles in the finished artwork. There's over 40 finished illustrations, so here's a small sample of some of them. All art copyright Space Dog Books 2011.
