Step 15: Use the remaining shapes and lines as guides to draw the rest of the pronghorn's head. Darken the outer edge of the top part of the guides to create the rest of the muzzle. Use quick, short strokes as you follow the guides at the bottom to create the lower jaw. Add a few strokes on the left side of the head for the hair found there.
Step 16: Use the line on the far right as a guide to draw the front leg that's on this side. Follow the path of the guide and lightly sketch the shape of the leg around it. When you get the shape of the pronghorn's leg right, darken the lines. Use quick, short strokes on the left side.
The shape of the leg should be wide at the top, and it should gradually get thinner toward the bottom. Bulge out the shape near the middle to indicate where the joints are on the leg. The pronghorn is walking, so the hooves should be pointing down. Add a few strokes inside the leg for the fur.
Step 17: Use the second line from the right as a guide to draw the pronghorn's other front leg the same way. Follow the basic path of the guide as you draw the shape of the leg around it. Bend the shape of the leg near the middle and add the hooves at the bottom.
Step 18: Use the line on the far left side as a guide to draw the first hind leg. Bend the leg near the middle and again close to the bottom to indicate the joints. The top part of the pronghorn's hind leg should be thicker than the top part of the front leg. Add some quick, short strokes for the fur.
Step 19: Use the last line under the body as a guide to draw the other hind leg the same way. Draw the pronghorn's hooves at the bottom. The top part of the leg will be hidden by the other leg, so don't worry about drawing it.
