"add a highlight opposite the first one becuase it is an orb."
Why? A sphere with one light focused on it shouldn't be reflecting light like that so far from its bottom edge.
edit: Spherize the selection one or two times to fix the shape of the light in the upper left (it should be elliptical, not circular. A sphere only reflects a circle when the light generated is at the same angles as the viewer's eyes). That's the advanced end of it
