the figure in motion

Here is where things get interesting , for me at least.  With the initial figure blocked out its time to trace the motion of the figure through time/space.

I think about the mechanics of the joints of the skeleton as well as the contraction of muscles to plot out the movement.  The human body is a beautiful combination of structural form and it follows certain laws of physics.  These can be learned through the study of structural anatomy.  Some years ago, when I worked in stop motion animation, I also studied movement by taking photographs in quick succession of the movement in question.
