Step 11: Just under the section where the two construction lines intersect, draw Agnes's nose. The nose is basically a curved line on top with a few smaller curved lines at the bottom for the nostrils.
Step 12: Draw Agnes's mouth under the nose and above the bottom edge of the main circle. The mouth is a long curved line with a couple of smaller lines on the sides for the smile lines. Add a small line under the mouth for the lower lip.
Step 13: Use the main circle as a guide to draw Agnes's face. The line for the side of the face starts near the eyebrow on the right, then moves down and out a bit to form the cheek. After that, just follow the the basic path of the bottom edge of the main circle as you darken the line to create Agnes's chin and jaw.
Step 14: Agnes's hair is a bit tricky, so it's divided into three parts. First draw front part of the hair or the bangs. Draw the top portion of the bangs as a long curved line at the top edge of the main circle. Then add the bottom part of the bangs by drawing a long jagged curved line just above the eyebrows.
Step 15: Now darken the guide line above the bangs to create the top part of Agnes's head and hair. Draw a long curved line on the left side of the head for the long clump of hair in front of the ears. The clump of hair on the right is mostly hidden behind Agnes's face, so only draw the curled tip of it.
