Step 11: Darken in Lisa Simpson's nose, making sure you curve the top part of the oval down slightly. Don't darken the right side of the oval.
Step 12: Darken in Lisa's eyes and draw pupils in the center of each circle. For the eye on the right, draw the pupil smack dab in the crosshairs. The pupil in the left eye should also be in the center on the horizontal construction line. Draw four short, slightly curved lines on top of each eye to represent this Simpsons character's eyelashes.
Step 13: Now learn how to draw Lisa Simpson's mouth, ear and neck. Tighten Lisa Simpson's mouth shape and draw a curved line at the end of her smile to indicate her laugh line. Darken in her ear and neck, and draw a slightly tilted and curved letter T inside her ear.
Step 14: When you darken in Lisa's hair, round out the triangle shapes to give her a more organic look. Darken in her necklace, too, but don't fill out the complete left-most circle. This pearl in Lisa's necklace is behind the second one.
Step 15: That's it! You now have now learned how to draw a sketch of The Simpsons character Lisa Simpson. You can stop at this quick drawing for a rough, sketchy look or go for a more finished look by continuing to the step below.
