Step 10: Darken the curved line on the top, left side of the head for the first part of the mountain goat's horn. Draw another curved line to the right to make the horn thicker. Make the tip pointy and the bottom wide. Close the shape at the bottom. Use the line on the right as a guide to draw the other horn the same way. Darken the guide and add a curved line to the right to make the horn thicker. Close the shape at the bottom.
Step 11: Darken the arc to the left of the horns for the ear but make the top part pointier. Stretch the bottom of the ear into the head. Add a curved line across the middle for the ear opening. Draw a series of short strokes within the shape for the fur found inside the ear. To the right of the mountain goat's horns, draw another small, pointy, arc-like shape with furry strokes inside for the other ear.
Step 12: Darken the top, right side of the initial circle but make the line more angular for the front of the head. Connect the head to the muzzle. Behind the mountain goat's horns, draw a series of short strokes for the furry top of the head. Draw a few short, curved lines around the eye to emphasize the bony brow. Add a few short strokes along the path of the initial arc at the bottom for the base of the goat's beard. Far down below the initial arc, draw a series of short strokes for the tips of the long beard. Add the strokes in a wavy pattern. The farther down you draw the strokes, the longer the beard will be.
Step 13: Use the second line from the right as a guide to draw the mountain goat's first front leg. Follow the path of the guide and lightly sketch the shape of the leg around it. When you get the shape of the leg right, darken the lines. Use short strokes at the top for fur. The shape of the leg should be wide at the top and gradually get thinner toward the bottom. Bend the bottom of the shape to indicate where the joint and top of the foot are. Draw a square like-shape at the bottom for the goat's hoof. Add a line across the shape to split the hoof.
Step 14: Use the angled line on the far left side as a guide to draw the hind leg the same way. Lightly sketch the shape of the mountain goat's leg around the guide. Bend the shape for the joints. The top of the leg should be very wide. When you get the shape of the leg right, darken the lines using short strokes for the fur. The bottom of the leg should be thin. Add the blocky hoof at the bottom and split it in half with a short line.
