This marks the beginning of the 'Dynamic Sketching' curriculum. At this point, I assume you've completed both lessons in The Basics section (Lesson 1 and Lesson 2). If you haven't, no matter how good you may be, I strongly recommend you complete them first. All the lessons on this website tackle drawing in a very specific manner, with specific techniques that are repeated throughout. These techniques are introduced in The Basics section, so if you miss them, you probably won't fully grasp what is explained here.
