Build an AI character reference sheet that survives new scenes

In this guide

An AI character reference sheet is a small, approved set of images that explains who the character is from the angles your content needs. Its job is to reduce ambiguity. A beautiful moodboard full of different faces does the opposite.

Separate identity from styling

Start with physical constants: face shape, species, hair silhouette, body proportions and distinctive marks. Put wardrobe, props and setting in separate groups. Otherwise, the model may treat a handbag strap or jacket collar as part of the character’s anatomy.

For Mallow, keep the ivory moth face, amber eyes and golden antennae. The burgundy jacket can be a default outfit, but a reference sheet should make clear where the jacket ends and the body begins. For a human character, check that eye spacing, hairline and profile agree across the selected images.

Choose views that answer real shot questions

• Front portrait: a clear, neutral view of the face and defining features.
• Three-quarter view: useful for conversational framing and turns.
• Side profile: important when the source clip rotates or walks across frame.
• Full body: establishes height relationships, limbs, posture and outfit proportions.
• Detail reference: only when an accessory or product must remain exact.

Use uncluttered lighting and a background that separates the silhouette. Do not hide the hands behind a prop in every image. If the planned content is seated close-ups, prioritize face angles; if it is dance, include a readable full-body view.

Approve each image against one master

Pick the strongest image as the identity master. Compare every additional view with it. Check ear position, nose shape, hair volume and the spacing of signature details. A profile that looks like a cousin is not a useful “extra angle.” Regenerate or remove it.

Keep the master and supporting views as separate high-quality files as well as a contact sheet for human review. The generation workflow may accept individual references rather than a composite sheet; follow its actual input requirements. Avoid uploading a contact sheet if the tool interprets multiple panels as multiple people.

Run a three-scene stress test

Use the references for a plain portrait, a different outfit and a short turn. Change one variable per test. If the portrait holds but the turn drifts, the missing information may be the profile. If a new outfit changes the body, the full-body reference may be unclear.

Version the library instead of silently replacing it

Use a naming convention such as mallow-front-approved-v03. Keep a short note explaining what changed and which posts used that version. When an older clip looks different, you can identify the reference rather than guessing which prompt caused it.

Do not approve a reference only because the face looks good at thumbnail size. Zoom in, then review it at the actual posting size. The goal is a usable foundation, not a perfect image collection. Add the approved files to the character bible and use the continuity workflow when movement introduces new errors.
