Quote - The way I see women, there are three areas that really seem to create a distinction between characters.  Nose shape, breasts, and belly button.  Everyone seems to have distinctly different shapes in these three areas and these, at least for me, tend to make/break a character.  You can put the same texture on a character but if you change these three areas, each character will appear different, sisters perhaps, but different.

That is interesting.  I've been noticing the importance of eyebrows recently, myself.  Their shape, placement and, particularly, how far apart they are.  This seems to make a surprising amount of difference when creating a character morph.  The distance between the eyes seems important, too.  I've never really noticed navels or, as you note in an unquoted part of your post, knees.  But variety in these areas does seem like it would contribute a lot to a character.
