Draw a copy of a figure in pencil done by any great master prior to 1900. It may be from a painting or a drawing. Some of the masters may include, but not be limited to, Rembrandt, Velazquez, Van Dyke, or Michelangelo. Look in Art History books and find a figure with which you "connect". If you are excited about the artwork you are copying, it will be apparent in your drawing.
Next, redraw the figure but only as a skeleton. Look at how the position of the bones relates to the pose of the figure. Include as many bones and as in much detail as possible. Skeleton Diagram
Bring in all 3: 1. the master artwork, 2. your copy, 3. the skeleton drawing.
