Step 11: Below the circle on the right, draw a couple of lines as guides for the centaur's front legs. The line on the left should be long and be bent slightly at the bottom. The line on the left should bend twice to indicate the lifted leg.
Step 12: Draw two long, angled lines under the circle on the left as guides for the hind legs. Bend the lines to indicate where the joints will be. Make your lines longer for a taller centaur. On the left side of the body, draw a long, curved line as a guide for the tail.
That's it for the guides! From this point on, press harder with your pencil for a more defined drawing.
Step 13: Inside the centaur's head, lightly sketch the eyebrows as two thin, long rectangles that are tilted slightly. Draw the eyebrows above the horizontal guide line. When you get the shapes right, darken the lines. The outer tips should be pointy, and the inner tips should curl a bit to emphasize the furrowed brow. Shade in the eyebrows using a dark value. Below each eyebrow, draw a thin, diamond- like shape for the centaur's eyes. Leave the insides blank for a menacing look. The eye on the right should be slightly smaller because of the tilt of the head.
Step 14: To the left of the eye on the right, draw a short, curved line for the bridge of the nose. Below that, near the bottom edge of the initial circle, draw a short, angled line for the tip of the nose. To the left, draw a couple of short, curved lines for the nostril. Pay attention to the distance between the centaur's nose and the eyes. Use the initial lines and shapes as guides.
