Step 10: Use more quick, short strokes to create the fur around the spider monkey's face inside the original circle. The fur line is wider at the top and narrower at the bottom of the face. The hairline curves down toward the sides of the mouth and forms the cheekbones.
Step 11: Use the initial circle as a guide to draw the rest of the spider monkey's head. Use quick, short strokes for the fur as you follow the basic path of the initial circle.
Step 12: Use the lines on the left side as guides to draw the spider monkey's arms. Follow the path of the guide as you make the arm thicker and use quick, short strokes for the fur. Make the arm skinnier at the top to create the wrist and add a few curved lines for the fingers. Use the line under the head as a guide to draw the other arm hanging down. This arm should bend a little near the middle because it's relaxed. Use a series of short curved lines at the tip of the hand for the fingers.
Step 13: Use the shapes in the middle as guides to draw the spider monkey's torso. Follow the path of the guides and use quick, short strokes for the furry texture. Add some fur inside too.
Step 14: Use the lines on the right side, under the body, as guides to draw the spider monkey's legs. Follow the basic path of the guide line as you make the shape of the leg thicker. Add the toes at the bottom. Bend the shapes of the legs to emphasize their relaxed state and hanging posture. Use quick, short strokes mostly on the right side of the legs. Don't forget to add the toes!
