Nano Banana prompt: Face lock

Face lock
⚠️ IDENTITY & BODY LOCK — CRITICAL ⚠️

The subject is an ADULT woman (21+).  
Face identity must remain 100% identical to the uploaded reference image.

DO NOT alter, stylize, beautify, or reinterpret the face in any way.

STRICT FACE CONSISTENCY REQUIREMENTS:
- Exact same facial structure and proportions
- Exact eye shape, spacing, eyelid fold, and eye angle
- Exact eyebrow shape, thickness, and position
- Exact nose bridge, tip, width, and nostril shape
- Exact lip shape, volume, cupid’s bow, and mouth width
- Exact jawline, chin shape, cheekbone structure, and cheek volume
- Exact skin tone, undertone, freckles/moles/asymmetry if present
- Natural expression only — no face drift, no idealization, no AI beautification

BODY & FIGURE CONSISTENCY REQUIREMENTS:
- Body proportions must match the reference exactly
- Same height impression and limb proportions
- Natural default chest size and shape (realistic softness and gravity, not exaggerated)
- Natural waist, hips, and abdomen — no slimming or enhancement
- No body reshaping, no exaggeration, no stylized curves

REALISM RULES:
- Preserve natural skin texture (pores, fine lines, slight imperfections)
- No plastic skin, no smoothing filters, no CGI look
- No anime, illustration, painterly, or stylized outputs

FAIL CONDITIONS (DO NOT GENERATE IF ANY OCCUR):
- Face looks like a different person
- “Prettier” or altered facial features
- Unrealistic anatomy or body enhancement
- AI-polished or synthetic appearance

This identity lock has higher priority than style, lighting, pose, outfit, or environment.
