The Secret to Drawing the Human Head from Any Angle
The human face is entirely responsible for the expressiveness, personality, and identity of a character. Yet, the vast majority of artists struggle to draw heads consistently from imagination. When attempting to draw a portrait, beginners usually focus on the "features"—the eyes, the nose, the lips—without understanding the 3-dimensional mass of the skull beneath them.
If you have ever drawn a face that looks "flat" or distorted when the character turns to a 3/4 view, you have experienced the limitations of drawing in 2D. To truly master head drawing, you must stop copying the details and start constructing the planes.
Understanding the Planes of the Face (The Asaro Head)
In the late 1970s, artist John Asaro created the "Asaro Head"—a sculptural tool designed to simplify the incredibly complex organic curves of the human face into distinct, flat planes. By breaking a smooth cheek into sharp geometric facets, artists could suddenly understand exactly how light and shadow interact with the form of the face.
Why the Interactive Tool Above is Brilliant
The free 3D interactive tool integrated at the top of this page is a powerful digital reimagining of classical planar reference models. It allows you to rotate the head 360 degrees and witness how structural planes shift in perspective. You cannot learn this from a 2D photograph.
The Loomis Method vs. Structural Invention
For decades, the standard text for head construction has been Andrew Loomis's classic ball-and-plane method. Loomis teaches you to start with a sphere, slice off the sides (to represent the flat sides of the skull), and drop a jawline down from that core mass.
While the Loomis method is an excellent entry point for beginners, professional character artists and concept designers often find it slightly rigid. By integrating the planar analysis of the Asaro head with the spherical foundation of the Loomis method, you arrive at true Structural Invention.
Proportions: The Golden Rules
When constructing a head from imagination, you must adhere to a strict set of internal measurements. While every human face is unique, these baseline proportions act as your architectural scaffolding:
- The Rule of Thirds: The face can generally be divided into three equal horizontal sections: from the hairline to the brow line; from the brow line to the bottom of the nose; and from the bottom of the nose to the bottom of the chin.
- The Width of an Eye: The distance between the two eyes is almost exactly the width of one eye. Similarly, the entire width of the head is typically "five eyes" wide.
- The Ear Alignment: The top of the ears aligns roughly with the brow ridge, while the bottom of the ears aligns roughly with the base of the nose. If a character tilts their head up, the ears appear to drop; if they tilt their head down, the ears appear to rise. This is the secret to drawing the head in extreme perspective!
Constructing the Features Mechanically
Once the basic block-in of the skull is complete, novice artists often fail when adding the features because they think of them as "stickers" pasted onto the face. Features are not flat; they are 3D volumes embedded into the skull.
The Eyes are Spheres
Never draw an eye as a flat almond shape. An eyeball is a literal sphere resting inside the bony socket of the skull. The eyelids have thickness and wrap around that sphere. If you draw the arc of the eyelids correctly, the eye will feel three-dimensional even without shading.
The Nose as a Wedge
The nose is the most prominent projection on the face. Before drawing nostrils or the bridge, construct a simple wedge shape protruding from the center line of the face. The bottom plane of this wedge (where the nostrils reside) will almost always be in cast shadow when lit from above.
The Mouth as a Cylinder
The teeth and jaws form a curving, cylindrical barrel under the skin (the dental cylinder). The lips do not sit flat on the face; they wrap around this curve. This means the corners of the mouth actually recede back into space, deeper into the face than the center of the lips.
How to Use This Free 3D Head Reference Tool
Do not simply look at the digital head embedded above. Use it actively to train your brain's spatial awareness:
- Rotate the model into an extreme upward angle (worm's eye view). Notice how the jawbone obscures the neck, and how you can see the underside of the chin and nose.
- Rotate the model into an extreme downward angle (bird's eye view). Observe how the forehead dominates the mass of the face, and the ears rise above the eyebrows on the horizontal axis.
- Sketch the major planes using a hard HB pencil in your sketchbook, focusing exclusively on finding the exact points where a plane changes direction.
Mastering the human head from imagination takes time, but it is entirely a mechanical, structural process. By memorizing these formulas and utilizing powerful 3D referencing tools, you can unlock the ability to draw compelling portraits from any angle imaginable.
