Nice way to put it, Shonner. Yah, for me, in descending order it is point of elbow, front of knee, lower rib margin, shoulder point that give it away. Also underside of raised arm and back of flexed knee. All but the latter are places where the underlying bone structure makes itself seen. But, and not to expand the discussion off the topic, it is the pose that gives it away to me in most Poser art. Apparently most people using Poser haven't seen a real human being in a while. They don't move organically, from inside. Contraposto is not conserved. The head doesn't lead the body. Sorry....didn't mean to hijack.
