  I'm not an expert on this kind of thing, so I'm open to doing more modifications. I still don't really get how the ambient shadow works vs the directional one.
  However, if an object casting a shadow is closer to the object in the shadow, the shadow will be darker than if the object casting the shadow is farther away.
  Try it right now with two pieces of paper under a ceiling light.
