Step 10: Darken the sides of the initial small circle to create the shape of the cougar's muzzle. As you darken the sides, use short strokes to create a fur-like texture. Add a few strokes above the nose to emphasize the top of the panther's muzzle.
Step 11: Darken the bottom edge of the small circle to create the puma's chin. Use short strokes to darken the edge for a fuzzy texture.
Step 12: Use the arc on the top, left side as a guide to draw the first ear. Darken the path of the arc but use short strokes along the top for fur. Add short strokes at the base of the arc too. Draw longer strokes within the arc for the fur found inside the mountain lion's ear.
Step 13: Use the arc on the top, right side as a guide to draw the cougar's other ear the same way. Darken the arc but make the sides wavier for a more organic shape. Add a series of short strokes within the arc for the fur found inside the ear.
Step 14: Use the main circle as a guide to draw the rest of the head. Use a series of short strokes along the top edge of the circle for the furry top of the head. On the right side, draw a curved line to form a bump next to the eye to emphasize the thick brow. Draw another bump farther down for the cougar's cheekbone. There should be a dip in the middle toward the eye.
Follow the edge of the circle on the lower, left side to create the rest of the mountain lion's head/jaw. Draw a series of broken up strokes along the edge of the circle to form the head/jaw. Add a few strokes inside the head for extra detail on the cougar's fur and structure. Draw a short line on the bottom and on the left side of the head for a small portion of the neck.
