A rare drawing by the Italian Baroque artist Gian Lorenzo Bernini is to go on sale on March 20 at an auction house in Compiegne, the French northern city where it was discovered six months ago.

I started breaking down human anatomy into simple forms to improve my figure drawing. In this first part, I focus on basic structure and proportions, using clean lines to map out the torso and limbs.

I use a simple step-by-step method to draw balanced face proportions. Starting with a circle and center line, I map out the jaw, ears, and features like the eyes, nose, and mouth using halfway points.
