Step 10: Near the bottom of the muzzle, lightly sketch a small curved shape for the nose. When you get the shape right, darken the lines but make the sides pointier so that it's more similar to a triangle. Add a couple of curved lines on the sides and shade them in for the pupils.
Step 11: Use the initial triangular line on the lower, left side as a guide to draw the markhor's muzzle. Darken the sides of the guide but make the shape more wavy at the top and use short strokes at the bottom for fur. Near the bottom of the guide draw a line that curves to the right for the mouth. Add short strokes around the mouth for fur.
Step 12: Use the long ling on the top, right side of the head as a guide to draw the base of the markor's horn. Draw the shape of the base around the bottom part of the guide line. This shape should be similar to a diamond that's tilted. Use short strokes along the bottom for fur. The bottom of the horn should be narrow and it shoud be inside the head. The top of the horn should be wide and curved.
Step 13: Draw the middle section of the markhor's horn around the guide line. This shape should be similar to an hourglass. Use a couple of angled lines on the right side and a wavier line for the left side. The top part of this section should be pretty flat.
Step 14: Finish drawing the top section of the markhor's horn around the top part of the guide line. This section is made up of smaller curved lines for the sides of the horn. The top should be thin and pointy. Pay attention to how the lines overlap each other to create the corkscrew shape of the horn.
