【白色在白纸上不太好表现，所以空出不画 表示白色。在有色卡纸上或者较软粉质彩铅 (覆盖性较好)当然没有问题】
Use White to burnish in the highlight areas and reflected light around the lips. Create the creases of the lips by burnishing White over the other colors with a firm touch. Do not overdo this detail because it will make the lips look aged.
用白色磨画高光区域和唇部周围的反光区 域，要用比较实的笔触将白色盖在其他颜色 上，不要将这一步做得太过否则嘴唇看起来 会显得上年纪。

Some students tell me that drawing the ear is the most confusing aspect of drawing a portrait. This is because most of us don’t pay much attention to this complex feature.
