here is a little example of the visual improvement
a shader can add to your model.
The sphere to the left uses a simple dull Diffuse shader,
the one to the right uses a Rim Light shader.
It adds a bit of contrast and color variation to the skin.
looks pretty good. :)
Thanks to Simon Wittber for this awesome little shader. :)
