I'll start with the left arm (Lex's right.) Unlock the layer, make sure you're on the first frame, and then select it with the Free Transform tool. You'll notice there's a little dot in the center of the square that outlines the area of the symbol; that's the pivot-point for the shape. You'll want to "grab" that point with your mouse and move it up to about the center-area on the shoulder, where the normal pivot point for a real arm would be. For the head you would move it to around where you would imagine the neck would join to the head--try to think in 3D for that and visualize what's behind the 2D perspective.
