To draw a mouth, create the outline of the lips, then shade the lips and soften the edges. Highlight each section of the lips using a pencil and blend the shading to promote realism.Continue Reading
Draw the line where the top and bottom lip meet. Curve the line down slightly in the middle, creating a subtle M shape. Draw the upper lip above the first line. Start with a straight diagonal line, then dip the line down sharply in the center to form a bow shape. Finish with another diagonal line connecting to the edge of the first line. Draw a curved line under the first line to form the bottom lip. The bottom lip should be fuller than the upper lip.
Draw a few vertical lines where the upper lip meets the center line. Draw vertical lines throughout the middle of the bottom lip.
Color the entire top lip in a dark tone. Draw a strong, darker outline on the center lip line and the vertical lines on the upper lip. Color the outside edges of the bottom lip in a dark shade. Color the first fourth of the bottom lip in a dark shade. Color the center of the bottom lip in a medium-dark shade.
Blend the dark sections with the light sections of the lips. Use a pencil or blotter to soften the edges of the completed mouth.
