Pirate ship in a night storm

One of the pirate books that I read to the kids had some beautiful illustrations of a stormy sea so I decided we should tackle some "stormy" art work. I felt like this subject would give an opportunity to talk about line movement and low value color schemes that can reflect a feeling of roughness and then when the lines become softer it reflects a feeling of calm and peace. The ship pictures were done with oil pastels and we tried to capture what it looked like when the ship was in a night storm.
