Shade the Lower Lip

Add Tones to the Lower Lip

Now we are ready to move on to the bottom lip.

Let’s add tones to the bottom lip similarly to how we did to the top lip. As you apply the vertical lines that will serve as the midtones for the bottom lip, it’s a good idea to not keep them exactly vertical. Instead, follow the curvature of the lip. Remember to work around the highlighted parts.

As you shade the core shadow along the bottom of the lip, remember to not shade over the strip of reflected light along the bottom edge. At first, shade in a similar vertical direction that follows the contours of the initial midtones, but feel free to shade over these darker tones of the core shadow in a horizonal direction after that. As you shade horizontally, bring some of these darker tones into the midtone area to create a more gradual transition.

Continue to shade horizontally over the lighter midtone areas now, creating a crosshatch pattern.

Looking at the photograph, we see some slight color variations in the midtone areas of the bottom lip, especially near the top edge of the bottom lip. Sketch these in now. Leave room for reflected light along the top edge of the lip too.

Blend the Tones of the Lower Lip

Use a blending stump to begin blending the tones of the lower lip. Begin in the lighter areas and work your way to blending the darker areas.

As you blend, it’s okay to smooth out the guideline borders of the lip highlights, as long as you don’t go too far into the highlights just yet. Blend the top outline of the bottom lip as well as the darker shadows.

Use a kneaded eraser to lift the strip of reflected light between the core shadow of the lip and the cast shadow that will be just under the lip and on the chin.

Add Darker Tones to the Lower Lip

Now we want to keep layering on some other darker tones. Namely, let’s apply another layer of darker values to the dark parts of the lower lip. Try to sketch in the same direction that you initially shaded.

Softly blend these darker areas with a blending stump.

Add Final Details to the Lower Lip

We are nearly finished with the lower lip!

With your kneaded eraser in a wedge shape, slightly lighten up some of the midtone areas by making some sideways streaks.

Also make a few up and down motions with your eraser to add to the lip’s texture.

Use the tortillion to put some overlap of graphite into the highlight areas. Try your best to mimic some of the vertical and sideways grooves of the lip.

Use your mechanical pencil to keep working some of the highlight areas. Draw in some vertical lines from the dark areas into the highlights, just like we did for the upper lip.

Use a tortillion to carefully go over the lines you just drew.

Make a wedge in your kneaded eraser to ride along the vertical lines of the bottom lip. Just like we did for the upper lip, try to lift highlights immediately adjacent to some of these vertical lines.

Where this reflected light is along the top edge of the bottom lip, I’m going to sharpen the outline of the lip to separate the reflected light from the gum line.

Then I’m going to lightly blend over it.

Let’s put a little more shading along the bottom just for some added texture.

Lightly blend over the marks with a tortillion.

Keep using your mechanical pencil, tortillion, and then kneaded eraser to build these layers of texture going along the bottom edge of the lip.

Now let’s work the left corner of the mouth, on our right side. We need a little more shading where the top and bottom lips meet each other.

With just a few quick swipes of our blending stump…

…our mouth is finally complete!
