STAGE 7: Here I take my tortillon, dirty or clean, doesn't matter. And go over the entire style in the direction of the hairs. Avoid crossing the strokes as much as possible to avoid a smudged look. Smooth everything out.
STAGE 8:Pick out highlights. I use my beloved "Hold-tu" putty and shape it into a sharp wedge. Then "draw" (drag) lines, uneven to each other, into the highlights so they blend into the pencil strokes and brighten the areas a bit. You could also do this with a sharp white eraser I'm sure, but the hold-tu works best for me.
Stay tuned for more of this portrait's stages. This concludes the hair tutorial. Thanks for the visit!
