It's weird how it takes other people to point out obvious flaws.
Some notes to make so I don't forget (regardless if anybody actually checks out this blog or not):
-Everything was too muddy.
-Skin looked oiled.
-Midway through this edited version, the skin was too yellow. Skin leans towards red as a local colour. Add the environment's yellow light and it should look good orange-tinted.
-Reference when doing realism.
-Contrast is ultimately determined by the intensity of the main light versus the secondary light(s). There is no such thing as the perfect contrast. It's relative to the environment.
More edits to come.
