How to draw a skull step by step.

Step 1: Start with the basic shapes and lines.

Draw a wide oval to represent the top portion of the skull. Then add lines that show where the jawbones come down to form the bottom of the skull. Add a vertical line down the center of the face, where the nasal cavity is. Keep in mind, this will not fall in the center of your drawing since the skull faces toward the side. Add horizontal lines to indicate the center of the eyeline, the bottom of the nasal cavity, and the center of the mouth. “Reference lines are like leaving yourself a map,” explains illustrator Ben House. “If you’ve left yourself a roadmap, you don’t have to keep looking at your reference photos, and you can have some fun.”

Step 2: Draw your eye sockets and nasal cavity.

Draw in your eye sockets and the cavern where the nose would be. “The nice thing with the skull is that the nose just gets to be a big hole in the face,” says House. The bottom of the nasal cavity should hit right where the round upper half of the skull meets the lower portion. Use your lines as a guide to place your eye holes both vertically and horizontally. The vertical center line of the face will be important for this step. “Without a center line, things can end up off-kilter,” says House. 

Step 3: Define the cheekbones and jawline.

Add more defined lines to the outer shape of the skull. The three-quarter view will highlight the contours of the temple, cheek, and jaw on the side of the skull that is partially obscured from view. Curves should jut out of the skull at the temple, cheekbone, upper jaw where the teeth are, and the bottom of the lower jaw or chin. “You’re going to find that you draw these lines a few times before you get them right,” says House.

Step 4: Add more detail to the top of the skull.

Add some more contour lines to the upper part of the skull. On a human skull, the temple line next to the eye socket curves around toward the back to outline an indented area on the side of the head. This should resemble a large, backward, and imperfectly shaped C. New curved lines can also be added to show where the right cheekbone is distinguished from the upper jaw and where the upper browline curves outward from between the eyes.

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.”
