In these three exercises – from Front, Side and ¾ View, he shows how to approach the lay-ins using the general proportions discussed previously. He then breaks the head down into their individual structures, defining the primary planes of the head first, then refining the individual structures, using the planes to help define the core and cast shadows and shading of the head. Lastly, Charles discusses the primary muscle groups of the human head, demonstrating each muscle's primary motion. These combined lectures provide a much deeper understanding of the human head and provides a strong foundation for drawing much more dynamic portraits.
