Step 15: Use the arc on the left as a guide to draw the sphynx's other ear the same way. Darken the shape of the arc using wavier lines and make the top part thinner. Draw a few short, curved lines at the bottom for the base and inner ear structure.
Step 16: Use the initial circle as a guide to draw the rest of the cat's head. Follow the path of the circle but make the top part of the head a bit thinner. Curve the lines around the eye on the left to emphasize the cranial structure. Draw a couple of curved lines below the ear on the right to make the shape of the head narrower. Draw a couple of curved lines below the eye on the right for the cheekbone. Add a series of short, curved lines on the sphynx's forehead for the wrinkly skin.
Step 17: Use the second line from the left as a guide to draw the sphynx's first front leg. Follow the path of the guide and lightly sketch the shape of the leg around it. Curve the shape where the guide bends to create the joint and foot. The top part should be thick and the bottom thin. When you get the shape of the leg right, darken the lines. Sphynx cats are hairless, so use smooth lines instead of short strokes to avoid a furry texture. Draw a couple of curved lines at the bottom for the toes. Draw a short line inside each toe for the cat's retracted claws. Draw a few lines at the top for the wrinkles on the loose skin.
Step 18: Use the line on the left as a guide to draw the sphynx's other front leg the same way. Draw the shape of the leg around the guide. Sketch lightly at first to get the shape right. Make the top part of the cat's leg wide and the bottom narrow. When you get the shape right, darken the lines. Draw a couple of short lines at the bottom for the toes and retracted claws.
Step 19: Use the angled line on the far right side as a guide to draw the cat's first hind leg. Follow the path of the guide and lightly sketch the shape of the leg around it. The top of the hind leg should be a lot wider than the top of the front leg. Curve the lines where the guide bends to create the joints. When you get the shape right, darken the lines. Draw a couple of curved lines at the bottom for the sphynx's toes. Inside each toe, draw a tiny line for the claws. Add a few short lines within the shape to give the leg more structure and wrinkles.
