Step 5: Outline the teeth.
Draw in teeth, and your skull will start to look eerily real. A reference photo can help, especially for the upper teeth, since most of us don’t usually draw the top part of teeth. If there’s an overbite, the tops of the lower teeth may be hidden. Remember to center your teeth with the same line of symmetry as when you placed the nose and eyes. Start with the front two teeth and build out from there. Imperfections and inconsistencies in shape will help here. “Teeth are not all uniform,” says House. “If you make them that way, it’ll look weird.”
Step 6: Add shading and final touches.
With the teeth in place, it’s time to add shading and more definition to your most important lines. The darkest areas on your skull should be the caves of the eye and nose, followed by the empty space underneath the cheekbones, where the jaws connect to the upper part of the skull. “Shading is where everything just pops to life,” says House. “You can get as detailed as you want.”
Draw skulls from different angles.
Practice drawing skulls from other views, like a true front view or side view, to get fully acquainted with the anatomy. When drawing a full profile of a skull, it can be important to remember that the spine doesn’t end at the bottom of the jaw; it goes up to the bottom of the back of the skull. “Everything connects to that little spot at the base of the skull,” says Elliott. “If you run your finger up the back of your neck, you can feel where it all connects.”
