Here is the image I am working on in postwork as you can see under her hair and on her shoulder the light is too much where it should be shadowed. Now I could just go back and rerender the whole thing adjusting the lights and waiting hours again to render or my other ideas is to paint shadows where they should be.

Normal I add shadows to the skin when I paint cloths using a soft brush 40% opacity painting the shadows on a new layer over the cloths then moving it down below it then gaussion blur it but not sure that would work I tried it and it looked to fake and horrible.

So now i am here asking if anyone else has any ideas I can try to get a good shadow effect between her shoulder and hair.
