There exists an endless cache of advice when it comes to figure drawing. Don’t believe any of it. If you follow a teacher or some online tutorial your work will suffer, be stiff, procedural, unoriginal and uninspired. Find your own path. Struggle and work it out for yourself. There is no secret. Draw what you see not what you think. Light, shadow, line. It is all there for you and no one else! Nothing is hidden. Be direct! There is no secret. Learn to look. Practice looking with a pencil and pad. Your own aesthetic and intuition will correct your way.
