Here is the rough paint job painted in photoshop with different size and textured brushes. I used a few layers, one for manin areas of clolr in body . On elayer for main body of hair layer. And two layers for smaller highlights in the hair and body, I adjusted opacitys,and blurred the highlight layers accordingly,until I was happy with the look. I imported into Adobe illustrator after the whole paint layer and drew the eyes and eye brows and nose line and body contours over the painting, I then went back into photoshop and overlayed the two layers the paint,and the line work seen below.
