Figure and Ground Relationship

For this series, I have decided to use a thick, dark line to outline the figure. You can see this in the detail above in the forward hand, arm, and leg. 

Where the shadow meets the edge of a drawing, as shown in the back hand and arm, I will usually not use a hard line.  This allows the dark values do the work of the line. 

With the rock overhead much of the figure is in shadow.  So both the rock and figure cast shadows on the ground.  I kept this shadow minimal so as not to overwhelm the figure.  However, I used the cast shadow to bring out the highlights and middle gray areas of the foot and leg.
