Gaunt planes head rotation reference

The gaunt head makes the cheekbone and the hollow beneath it useful construction landmarks. Compare the width across the cheekbones with the narrower mouth and chin. A dark hollow can look like a contour in the tonal drawing; check the line view to see whether it actually changes the silhouette. Follow the jaw back toward the ear before placing the neck, keeping the lean face attached to the larger skull.
