保持身份特征的发型拼贴提示

Use case: identity-preserve style-transfer Asset type: vertical 3-by-3 portrait hairstyle collage for a social post Create nine close-up beauty portraits of the same woman, using the uploaded portrait photo as the appearance reference for the person. The most important requirement is facial likeness: preserve her rounded oval face shape, soft youthful facial proportions, large round brown eyes with the same eye spacing, gentle natural eyelids, straight soft brows, small rounded nose, subtle smile, natural peach lips, smooth jawline, narrow chin, warm fair skin tone, center-parted dark brown hairline direction, and overall gentle expression. Keep the same facial geometry, gaze, expression, and identity in every panel; only the hairstyle and hair accessory should change. Scene/backdrop: seamless warm pink-beige studio background, clean salon portrait look, no props except hair accessories. Subject: the same young woman in all nine panels, front-facing or nearly front-facing, upper chest to head crop, relaxed shoulders, simple light knit or bare-shoulder styling, gentle closed-mouth smile, direct natural eye contact. Style/medium: photorealistic polished Asian beauty editorial with realistic identity preservation, soft K-beauty lighting, believable skin texture, visible natural pores, no doll-like beautification. Composition/framing: vertical 3x3 grid collage, nine equal panels, each panel centered on the face, consistent camera distance and facial scale, balanced spacing, clean edges, no labels. Hairstyles by panel: twin low ponytails with plush bear clips; high bun with a delicate rhinestone tiara; high side ponytail with a soft scrunchie; loose side braid; short softly curled bob with straight airy bangs; tidy low bun with wispy bangs; long voluminous natural curls; long waves with a knitted headband; long layered waves with airy curtain bangs. Lighting/mood: warm diffused studio light from front-left, gentle fill, soft highlights on hair, luminous but natural skin, romantic soft mood. Color palette: pink beige, warm cream, chestnut dark brown hair, soft peach blush, natural coral-pink lips. Textures/retouching: detailed glossy hair strands, realistic skin pores, natural eyelashes, light makeup, subtle catchlights, high resolution. Constraints: identity match is more important than changing face beauty style; preserve the person's recognizable appearance from the uploaded portrait photo; keep the same face across all nine panels; change hairstyle only; no watermark; no logo; no text. Avoid: generic Korean idol face, different person, changed eye shape, smaller eyes, sharper chin, altered nose, altered lips, altered eyebrows, changed smile, changed face width, inconsistent identity across panels, over-beautified face, plastic skin, doll face, repeated hairstyle, distorted grid.
