Step 15: Darken the initial circle to create the shape of the cheetah's head. Make the right side of the head a bit thinner than the circle. Use short strokes to represent fur.
Step 16: Use the line on the left side as a guide to draw the first front leg. Follow the path of the guide and lightly sketch the shape of the cheetah's leg around it. The leg should bend forward a bit at the bottom. When you get the shape right, darken the lines. Use short strokes at the top for fur. Draw a couple of curved lines at the tip of the foot for the toes. At the front of each toe, draw a small, pointy shape for the big cat's claws. The top part of the leg should be wider than the bottom.
Step 17: Use the cheetah's first leg as a template to draw the other front leg on the left side. Most of this leg will be behind the first one, so only draw the left edge and the toes.
Step 18: Use the line on the right side as a guide to draw the first hind leg. Lightly sketch the shape of the leg around the guide. Pay attention to how the guide bends. The top part of this leg should be a lot wider than the top part of the front leg. When you get the shape of the leg right, darken the lines. At the bottom, add a couple of curved lines for the toes. Draw pointy shapes in front of the toes for the cheetah's claws.
Step 19: To the left, draw a line parallel to the first hind leg for the other hind leg. Only draw the left edge of this leg. Add the cheetah's toes and claws at the bottom too.
