I postwork almost all of my images to some degree. First I always check limb joints for cracks as Diolma says and I blur and smudge till they look right. Then I usually use one of Bloodsong's hair brushes to roughen the outline of the hair and add a few wispy strands. Most hair props have smooth crowns and edges that you never see in the real world. Then I apply any filters I think are needed. I usually look at Auto-contrast and Auto-level to see if these improve things and I tend to play around with colour curves.
