Anna is an original fictional female character created for cinematic storytelling, virtual production, concept art and consistent character generation.
This Character LoRA was trained for Tongyi-MAI/Z-Image-Turbo. It is designed to preserve Anna's recognizable facial identity across different camera angles, expressions, hairstyles, clothes, lighting conditions, locations and historical or science-fiction settings.
Anna has a mature Mediterranean appearance, very dark brown hair, gray-green hazel eyes and a calm, intelligent and self-assured cinematic presence. She is intended to function as a reusable virtual actress rather than as a single fixed portrait.
Anna is an original fictional character and is not intended to represent any real person.

What this LoRA does
The LoRA adds Anna's identity to Z-Image Turbo. It can be used to generate:
close-up and medium cinematic portraits;
three-quarter and profile views;
full-body compositions;
different facial expressions and emotions;
contemporary, historical and science-fiction costumes;
natural daylight, studio lighting and dramatic cinematic lighting;
recurring images of the same character for storyboards, films and visual narratives.
The LoRA controls the character identity. The surrounding scene, clothing, pose, expression, camera and lighting should still be described in the prompt.
Installation in ComfyUI
Download ANA_IDENTITY_ZIMAGE_V1.safetensors.
Copy it into:
ComfyUI/models/loras/
Restart ComfyUI, or refresh its model list.
Load Z-Image Turbo as the base model.
Add a LoRA Loader node and select ANA_IDENTITY_ZIMAGE_V1.safetensors.
Start with a LoRA strength between 0.8 and 1.0.
Include the trigger ana_biosyn near the beginning of the prompt.

These are starting values rather than absolute requirements. A lower strength can give the prompt more freedom, while a higher strength can reinforce Anna's identity.
Trigger word
ana_biosyn
For best identity retention, use ana_biosyn woman close to the beginning of the prompt.

Prompting advice
Put ana_biosyn woman near the beginning of the prompt.
Describe the desired framing explicitly: close-up, chest-up, three-quarter view, profile or full-body.
Describe expression, clothing, lighting and location separately.
If the identity becomes too dominant or the pose too rigid, reduce the LoRA strength.
If facial identity becomes too weak, move the trigger earlier and slightly increase the strength.
For comparisons, keep the same prompt and seed while changing only the LoRA strength.
Current limitations
Identity consistency can vary in very distant full-body shots.
Extreme camera angles, heavy facial occlusion or highly stylized rendering may reduce resemblance.
Complex scenes containing several similar female characters can cause identity mixing.
Recommended strength is still being evaluated and may be refined in a later version.
Results depend on the exact ComfyUI Z-Image Turbo workflow and its model versions.
