COMMENT August 22, 2014: I see now - after doing several lighting tutorials - that I need to adjust my lights to avoid getting those visible dark lines on her face. I may post an updated render later on.
NOTE: No postwork has been done on this render. Just learning. :)
The following image is a render with the same lighting as the first image. The addition of the hair resulted in a big increase in render time due to transparency of the hair.
