Lesson 10: Formulas for the Side View of the Human Head - Phase 2

In Lesson 10, we reach Phase 2 of the Side View Formulas. This is where we strip away the "training wheels" of the bounding box and transition into what Riven Phoenix calls the Peg System. This lesson is fundamental for artists who want to move beyond copying reference and start generating complex anatomy purely from memory.

The Peg System: Using specific anatomical landmarks as "mental anchors" to reconstruct the head on the fly.

The Peg System and Memory Management

Most art education fails because it asks students to memorize a finished result. The Structure of Man uses a "Peg System"—a memory management technique that links anatomical facts to simple geometric actions. Instead of remembering a whole skull, you remember "pegs" (like the intersection of the jaw and cranium) and the "sentences" (the lines) that connect them.

By the end of this lesson, you transition from drawing boxes to drawing with intent. You understand how to "eyeball" proportions because your mind has been trained to recognize the structural logic behind every subdivision established in Phase 1.

Ultimate Simplification: Replacing the rigid box with a simple 'plus sign' to trigger the entire construction formula.

The Plus Sign Simplification

To prove you have mastered the formula, Riven demonstrates how to build a realistic human skull starting with nothing but a plus sign (+). This cross establishes the core axis of the head. From this single intersection, you can mathematically determine the jaw depth, the cranium's height, and the angle of the neck.

This allows for a "sketchy," organic style that still maintains 100% anatomical accuracy. You are no longer trapped by a rigid grid; the grid now exists invisibly in your mind, allowing you to draw the skull from any starting point with total confidence.

Character Invention: Adjusting the formula's variables to create diverse head shapes and racial features.

Character Variation and Diversity

A common fear of using formulas is that every drawing will look the same. Lesson 10 dispels this myth. By understanding the "sentences of the formula," you can purposefully "mispronounce" them to create different characters. You can elongate the jaw, flatten the cranium, or adjust the nasal angle to create unique individuals while keeping them structurally sound.

This is the secret to Character Design at a professional level. You aren't guessing what looks "cool"—you are making logical adjustments to a proven skeletal base, ensuring that even the most stylized characters feel grounded in reality.

The Ear Alignment: The top of the ear must align with the brow ridge, and the bottom must align with the nose.

The Ear Placement Formula

Finally, we master the Ear Formula. The ear is often a "floating feature" for beginners. Lesson 10 provides a rigid rule: the ear canal sits precisely at the vertical center of the head, where the jaw connects. Vertically, the top of the ear aligns with the brow ridge (the brow "peg"), and the bottom aligns with the base of the nose (the nose "peg").

This alignment remains true across almost all human variations, providing a "golden rule" that instantly improves the believability of your profile portraits. With Phase 2 complete, the skeletal foundation of the side view is fully mastered.
