this was a demo for one of my recent plein air classes. i hired a model and took everybody out on the beach to paint "mudheads" ala cape school tradition. also had a lot of inspiration from peggy kroll roberts dvds. the feeling of light and simplicity of drawing were my main goals with the class of mostly novice plein air painters. keeping the values in the shadows close (and the values in the light area as well) helps to simplify the process as well.
