Students began drawings addressing light and dark value rhythms and simulated textures. Light and dark rhythms create directional movement through a composition by employing similar values and textures. Simulated textures are an artisit's interpretation of actual textures. Patrick's drawing above has yet to address the values though even at this stage a rhythm has been establish by repeating similar forms and textures. Notice how your eye wanders through the composition following a path the the sunflowers.
