Amy, Angie and Chris.
In the photo above, Amy demonstrates near perfect overhead position. Her midline is rigid, her legs are turned on and her shoulder angle is open with her armpits forward and the bar cutting her in half. Angie has the second best position in the photo. Her legs and migline are active but inflexability make it difficult for her to open her shouder angle as much as Amy, still a good overhead position. Chris has two major faults going on. One, the bar is too far behind the head and two, the ribs cage is flying making it hard to stabailize the load. If chris were to pull his head up, his ribs down and move the bar forward just a little he would look much more like Amy and therefore be in much better position.
