No he's not drawing the contour. Do a quick google search for contour drawing. You will see how these drawings go straight for detail and often end up looking stiff and flat. http://imgur.com/zIX9uCJ this is one of my gesture drawing. I don't really ever start with the head like Proko does because I tend to find my torso/spine then ground myself. The gesture is to mostly help you find the 'force' in the figure but I also use the ribcage, elbows, knees and ankles to help me measure the body in relation to itself. http://imgur.com/26Jni4v This guy is suppose to be using a bow. It's a weird pose especially since his arm is out and it's easy to lose just how far out that arm goes.... So I used it's relation to the jut out leg to figure out it's distance but also that foot's distance to the grounded knee. I l mean, I'm doing too much feeling around and not confidentially putting down a line. At least this is simple and loose enough I can adjust the pose.
