Step 10: Under the lion's nose, draw a line that curves to the right for the first half of the mouth. The line should stretch all the way to the edge of the big initial circle. Use short strokes for fur. To the left, draw a shorter, sloping line for the other side of the big cat's mouth.
Step 11: Darken the bottom edge of the initial muzzle circle to create the chin. Use a series of short strokes as you follow the path of the circle to create a furry texture. Stretch the right tip of the line so that it curves inside the head.
Step 12: Draw a long, sloping line from the big cat's nose to the left eye for the top part of the muzzle. Darken the left side of the initial circle to create the side of the muzzle. Curve the side of the muzzle inward so that it connects to the lioness' mouth. Draw a series of short lines between the eye on the right and the nose to give the muzzle more structure.
Step 13: Use the arc on the top, right side of the head as a guide to draw the lion's first ear. Draw a series of short strokes along the edge of the arc to make the ear more furry. Make the bottoms of the arc longer so that the lines stretch inside the head. Stretch the right tip of the ear lower than the horizontal construction line and curve it to the left. Inside the big cat's ear, draw a smaller arc that's made up of short strokes for the ear's furry opening. Draw longer strokes across the ear and along the bottom for more fur.
Step 14: Use the arc on the left as a guide to draw the lion's other ear the same way. Use short strokes along the edge to make the ear furry and curve the lower, left side a bit. Draw a wavy line inside the ear that's made up of strokes for the ear's opening. Draw a series of longer strokes across the big cat's ear for more fur.
