Step 10: At the top of the small circle, draw a thin shape that curves to the right for the top of the head. The shape of Oogie Boogie's head is wide at the bottom and narrower toward the tip. The lines for the bottom edge of the head should curve until the tip touches the edge of the initial circle again. Make the tip round and then curve the line back up to meet the top edge of the head.
Step 11: On the left side, draw a line from the eye to the mouth for the left side of Oogie Boogie's head. On the right, draw another curved line for the other side of the head. Follow the basic path of the initial circle as you draw the shape of the head. Draw a few short lines along the lower edge of the circle for the creases on the burlap-like skin.
Step 12: Darken the curved line on the left to start forming the shape of Oogie Boogie's first arm. Make the bottom tip curved and thin. Then draw a line that curves up again for the inner edge of the arm. Draw another line at the top, along the edge of the big initial circle, to complete this Nightmare Before Christmas character's arm.
Step 13: Use the curved line on the right as a guide to draw Oogie Boogie's other arm the same way. First darken the guide to create the outer edge of the folded arm. At the bottom, use a couple of curved lines to create the thin, round tip of the hand. Draw a curved line along the top edge of the initial circle to complete the shape of Oogie Boogie's arm.
Step 14: Darken the sides of the big circle for the body. Add an extra bump at the bottom for the tops of the legs. Draw a long, horizontal line along the bottom edge of the initial circle for the bottom of the body. Draw a line across the torso to emphasize Oogie Boogie's big belly.
