Here's a 'browser buster' image of the original for example... no modifications here.  I didn't even watermark it yet ** Take note that its shot at 400 ISO.  Click on the image to see the full size.
Someone said no girl is perfect, and needs to be touched up.  Well I find that if you get 'clean', natural 18-21 year olds, they usually don't need any touchups.  So I can get away with it.
Natural textures, instead of 'over airbrushing' feels less plastic, more natural, and far more erotic in my opinion.  You could almost kiss this face.
