Contour Cavity Drawing of a Skull
As you begin drawing on a higher level you will discover that there are many ways to capture the form of a subject. The method that I want you to learn is what I call the contour cavity technique. The steps are quite simple. We will jump start this process by using a light tablet and a photo of a human skeleton. Using tracing paper copy the image using a pencil and create contour outlines or cavities of the highlights and values of the skeleton. After you complete the contour cavities then go back and complete your drawing by adding shading, blending, and gradations.
