I remember when you would write a desc and then commission an artist to draw it. Do people still do that? I miss it. I LOVED to see how a person took a desc and some personality questions and drew them.
As for realism. Meh. I don't really care about PB. Sometimes I will look at them to see what the player thinks their char looks like in their brain. Mostly, I jump on a wiki to look at known information to see what I can draw a story with. Or what color eyes/hair they have to add into my pose.
