Step 10: Under the nose, lightly sketch a line that curves to the left for the first half of the jaguar's mouth. The line should stretch all the way to the left edge of the muzzle circle. When you get the shape right, darken the line using a series of short strokes for the fur. Draw a shorter curved line on the right side for the other part of the mouth.

Step 11: Darken the bottom edge of the initial muzzle circle to create the jaguar's chin. Use a series of short strokes as you follow the path of the circle to create a furry texture. Curve the line on the left so that it ends slightly outside of the muzzle circle.

Step 12: Darken the right side of the initial circle to create the side of the jaguar's muzzle. Curve the right side of the mouth up to the side of the muzzle. Add some lines above the nose for the top of the muzzle. Break up the lines for a furry texture. Add a curved line made up of short strokes on the left to complete the big cat's muzzle.

Step 13: Darken the arc on the top, left side of the head to create the big cat's ear. Make the lines longer at the bottom. Draw a series of short strokes within the arc for the furry ear opening. Use longer strokes to create the longer fur found inside the jaguar's ears.

Step 14: Draw the jaguar's other ear the same way. First darken the initial arc to create the shape of the ear. The add a series of short strokes within the arc for the fur inside the cat's ear.
