Step 11: Under Vanellope's upper lip, draw two smaller lines that curve up for the bottom lip.
Step 12: Use the main circle as a guide to draw Vanellope'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 Vanellope's chin and jaw.
Step 13: Vanellope's hair is a bit tricky, so it's divided into a few parts. First draw the front left part of the hair or the bangs. Draw the top portion of the bangs by darkening the left edge of the main circle. Then add a series of curved, spiky lines across the top part of the eyebrow on the left and down to the lower left side.
Step 14: Now draw the right side of Vanellope's bangs in a similar way. Use the to edge of the main circle to draw the top part of the bangs. The right side should be closer to Vanellope's face and end in a couple of curved spikes. The lower part of the bangs should be high above the eyebrow on the right.
Step 15: Use the C-shaped line on the left side as a guide to draw Vanellope's ear. Draw a couple of curved lines within the shape for the ear's structure. Draw another curved line on the left side of the head for the other ear and two tiny lines under the head for the neck.
