For the shipwreck scene, I wanted to mimic antique oil paintings of storms at sea. The first three images by masters of the genre represent the kind of nautical art to which I would be tipping my hat.
Following those are my own work. By now you know the drill: thumbnail sketch, tight sketch, color study, final illustration.
The thumbnail sketches are each about 2″ tall, the tight sketch is maybe 8″ tall, the color study is the size of a postcard, the final is about 20″ x 14″.
