yeah, it's kind of tricky. . .
you cannot get the hair different than the shape of the head already. it just paints it onto the shape of the default head.
you also need 2 shots. front of face with both eyes, mouth and both ears showing. and a profile with only one eye showing, nose at the edge and one ear hole showing. the pics are kinda hard to find, but i got it to work with a pic of prez bush. . . hahaha it was lots of fun
