小提醒：
1. 側鋒 輕下筆
2. 找inner curves
3. 畫 what figure is doing
4. Unify the body using simple, curving lines，且總線數越少越好

Part 1. Primary action line

Part 2. Figure in Action

Part 3. Axis lines

Part 4. Torso

Part 5. Center line

突然發現錯字 是linea alba

Part 6. The legs

Part 7. The feet

注意觀察 gesture 先於細節

Part 8. The upper torso

Part 9. The arm

Part 10. The Hands

Part 11. Head and Neck

因為是gesture drawing, 所以提的不多，抓形＋眼睛線＋jaw line+SCM

注意，側面中代表neurocranium的蛋形，軸不是水平的

Part 12. Light and Shadow

先抓大致的明暗交界線，form shadow and cast shadow
細節在之前教光影的課有講過

不要見樹不見林
