You are right, too much SSS often gives a waxy look. OK for statuettes but, as far as flesh is concern, good looking SSS is an art in itself...
Because of the lighting of the first image (V10 beauty 2), I was expecting more transparency in the ear. It's all a matter of taste for in the real world, SSS isn't always visible or strong. Lighting, composition and thickness of the skin, blood flow, age and numerous other factors plays in the amount of SSS visible.
