Step 10: Inside each eye, right above the eyelids, add a dot for the eyes. Draw a line above the eyes and some short lines on the sides for his wrinkles. Draw a couple more lines at the bottom for the bags under Muscle Man's eyes.
Step 11: Draw Muscle Man's mouth under the nose by first drawing a small line on the right. Then, using a curved line, draw the shape of the open mouth. The shape of the mouth should be similar to a sausage link.
Step 12: Inside Muscle Man's mouth, on the top side, draw three small, u- shaped lines for the teeth.
Step 13: Use the initial lines as guides to draw the first part of Muscle Man's hair. Draw a series of small, u-shaped lines along the top part of the original rectangle. Follow the basic path of the guides to draw the right side of the hair. Use small u- shaped lines along the bottom for the tips of the hair.
Step 14: Now draw the second part of Muscle Man's hair by first drawing a couple of small, curved lines on the top right. Then follow the basic path of the guide as you draw a long, curved line for the top of the hair. Use two small, u-shaped lines on the left to indicate his bangs. Finish Muscle Man's hair by drawing the left side and adding the curved tips at the bottom.
