You first want to start with doing the outlines of the arm. Basic shapes like tubes are given structure with cross sections. This is to know if your knee is bending or is it straight. To do a gesture properly is to use landmarks. You start from the toes positioning and work your way up from here. Your feet, knee, and torso are your three landmarks. Erasing sharp edges helps to give the effect of a more soft drawing and the limbs seem more realistic. Today we learned that drawing is more about posture than about the drawing itself.
