From the line at the hips, draw two angled lines for legs that are 4 heads long.
At the ends of the two leg lines, draw two small triangles for feet
After you become proficient at drawing using heads to determine proportion, just create a series of hash marks to mark off lengths equal to the height of the head — you don’t need to draw full ovals. This shortcut helps save time and decreases the amount of erasing you need to do.
