Silhouette and overlap
While not necessarily used in this workshop, these are essential in making a picture as readable as possible. Silhouettes describe the figure and their actions. If the figure/object doesn’t read as a silhouette then change the pose or orientation. Overlap occurs when one object that’s in front of another creates the illusion of depth. See the art of Howard Pyle, NC Wyeth, Harvey Dunn, Dean Cornwell, Frank Frazetta and Jeff Jones, among others.
