From the resource, “Figure Drawing for all it’s Worth by Andrew Loomis”, based on the “8 head Ideal Figure” How can we draw a variety of figures and maintain the individual character of each person and keep it from looking formulaic? How can we capture animation and still maintain good proportions?  Peggi uses what she calls “vicinity marks”. These marks indicate where a specific part of the anatomy should land or come close to and it works every time. Then with solid contour drawing specific to the individual, you will capture a real variety of people. “I rely on these marks, especially when trying to draw moving figures. This can be very frustrating. But with these marks and some memory work I can get very close and build believable figures.”  See some video stills here.
