📐 The 2-Reference System

The foundation of it all: what each reference controls and why a clean split makes the results repeatable.

What it is:

Reference 1 locks in the identity: facial structure, facial proportions, skin tone, hairstyle, and the character's recognizable appearance.

Why learn:

It’s what ensures that, in any style, it’s still the same person. Without it, each generation becomes a different character.

Key concepts:

Identity = face + proportions + skin + hair + “look.” Never delegate this to Reference 2.

What it is:

Reference 2 guides only the outfit's design: silhouette, fabric type, accessories, color palette, and styling mood.

Why learn:

You borrow fashion language without importing the face from Ref 2—so the outfit changes, but the person doesn’t.

Key concepts:

"Use Reference 2 ONLY for the outfit." That sentence appears in every prompt for a reason.

What it is:

Each prompt explicitly instructs you NOT to copy the pose from any reference and to create a new, specific pose.

Why learn:

It’s what sets “moving the character through worlds” apart from “repainting the same image.” The new pose adds life and variety.

Key concepts:

Describe the pose in detail (sitting, contrapposto, three-quarter view) — vague prompts produce generic results.

What it is:

The deliberate separation between who the person is (Ref 1) and how the world is styled (Ref 2 + genre).

Why learn:

When identity and clothing inspiration get mixed together, the results become random. The split keeps everything predictable.

Key concepts:

One prompt = two clear sources. Mix them up and you lose control.

What it is:

The workflow: keep the face consistent, change the visual genre, and create a new pose every time.

Why learn:

It’s what makes the prompts useful for repeatable character design at scale — a brand, an avatar, a series.

Key concepts:

Lock face → change genre → new pose. Three steps, endless variations.

What it is:

The system is consistent because the face comes from one reference and the fashion from another — without locking the image into a single pose.

Why learn:

Understanding the “why” lets you adapt the system to any new style, not just the 10 in the pack.

Key concepts:

Strong identity + strong visual genre = a result that’s recognizable and varied at the same time.

🎨 Library of 10 Prompts

The ten character design directions. Each keeps the same person and changes the world, rendering logic, and narrative framing.

What it is:

Surreal editorial oil painting: vintage lounge, bizarre animals, expressive brushstrokes, confident seated pose.

Why learn:

Shows that the system works even in sophisticated, absurd-at-the-same-time “gallery” styles.

Key concepts:

Lowbrow + café culture + 4:5 vertical. Full prompt in the module.

What it is:

Ugly marker and crayon drawing: crooked proportions, scribbly lines, intentionally bad meme energy.

Why learn:

Proving identity in a "low-quality" style is difficult—and that's exactly where face lock shines.

Key concepts:

Explicitly request "NOT realistic, NOT polished". Deliberate chaos.

What it is:

Skin shop card: blue gradient background, rarity banner, fictional V-Bucks prices, full-body render.

Why learn:

Interface layout + recognizable character = collectible. Don’t copy text from a real brand.

Key concepts:

Fictional cosmetic icons + polished stylized realism.

What it is:

Anime/concept art champion poster with original creatures around the subject and a heroic three-quarter pose.

Why learn:

Combines semi-realistic painting, a Japanese magazine cover, and premium trading-card art in a single prompt.

Key concepts:

Original creatures (do not copy IP) + minimalist cream background.

What it is:

8K portrait in the style of open-world promotional art: neon, wet asphalt, luxury car, calm attitude.

Why learn:

Shows cinematic grading and poster typography — an AAA game cover look.

Key concepts:

Inspired by the style, without using a real brand. Fictional typography and seals.

What it is:

Superhero editorial portrait: metallic black suit with geometric patterns, helmet at the side, giant mechanical zord behind.

Why learn:

Here, Ref 2 inspires the fashion, but the outfit is transformed into a new concept (black, not blue).

Key concepts:

Low angle + golden hour + minimalist futuristic HUD.

What it is:

Plasticine caricature: noodle-like limbs, oversized hands, misaligned eyes, handmade clay texture.

Why learn:

Stop-motion style tests the limits of recognizability—exaggerated features, but still “the person.”

Key concepts:

Miniature setting + macro depth of field + outfit recreated as clay fabric.

What it is:

Hand-drawn ID card: crooked text, stickers, fake stamps, portrait with a goofy smile.

Why learn:

Document + doodle mix: structured layout with deliberately chaotic execution.

Key concepts:

Fictional, silly details. Must NOT look like a real document.

What it is:

Grotesque fashion caricature: stretched anatomy, dramatic pose, handwritten annotations, and fake fashion ratings.

Why learn:

"Editorial analysis" page from a strange sketchbook—exaggeration with purpose.

Key concepts:

Messy ink + watercolor + aged beige paper.

What it is:

Designer toy portrait: soft Pixar-style CGI + street fashion vinyl, glossy accessories, patches, and badges.

Why learn:

Wraps up the pack with a premium, futuristic, cute collectible style.

Key concepts:

Subsurface scattering + product photography lighting + studio gradient.

🧪 Extra Variations & How to Reproduce

The system extends to even stranger variations — and the step-by-step process for reproducing everything at high quality.

What it is:

A second take on the clay figure, showing that the identity lock holds up to extreme exaggeration.

Why learn:

Variations within the same genre expand the set without creating prompts from scratch.

Key concepts:

Reuse the style language, change the pose and props.

What it is:

Fake ID humor: another way to show that document and doodle can coexist.

Why learn:

Shows how rigid layout and chaotic execution create memorable results.

Key concepts:

Strong identity survives even in a “bad on purpose” style.

What it is:

Grotesque fashion sketch language pushed to the extreme, with sarcastic annotations.

Why learn:

Confirms that "sketchbook" styles work when the identity lock is strong enough.

Key concepts:

Strange haute couture silhouette + fabric callouts.

What it is:

The face comes from one reference and the fashion from another — so the result is recognizable without being locked into a pose.

Why learn:

It’s the principle you can carry over to any new style you come up with.

Key concepts:

Fixed identity + flexible styling = repeatability.

What it is:

Oil painting, doodle, game render, anime poster, open-world promo, sentai editorial, clay, fake ID, sketch, and CGI toy.

Why learn:

Clearly defined visual genres produce very different outputs of the same person.

Key concepts:

The more specific the genre, the more distinctive the result.

What it is:

The step-by-step process for generating: choose a model, lock in the identity, describe the world, and iterate on the pose.

Why learn:

From concept to practice—including how the images in this guide were made locally.

Key concepts:

An edit-capable model for 2 refs; T2I for a single style. Iterate cheaply, finalize at high quality.
