Square mockup of a large transit advertising panel inside a modern subway station, bold cobalt, coral and cream geometric campaign with a central abstract skincare silhouette. No readable text, no logo, no watermark.

Transform the person in the reference photo into a luxurious Korean subway station birthday advertisement billboard (birthday billboard). This must look like a professionally designed K-POP idol birthday ad printed on a wide horizontal digital display. === PERSON (RIGHT SIDE, ~40% of frame) === - Place the person on the RIGHT side of the image, framed from the CHEST UP (medium close-up portrait). - PRESERVE the person's EXACT face, facial features, skin tone, eye shape, nose, lips, and hairstyle from the reference photo. Do NOT alter their identity in any way. - Expression: gentle, warm, soft natural smile — friendly and celebratory. - Pose: shoulders relaxed, turned very slightly toward center, looking directly at the camera. - Outfit: replace with an elegant, delicate cream/ivory ruffled blouse or knit top. Add a thin gold chain necklace with a small pendant. - Apply soft, flattering, diffused beauty lighting on the face — no harsh shadows. Subtle rim light / halo effect on hair and shoulders from behind. === TEXT & LAYOUT (LEFT SIDE, ~60% of frame) === All text is CENTER-ALIGNED and stacked vertically on the LEFT side of the image: 1. [TOP] A small, delicate gold line-art crown or filigree flourish ornament, centered. 2. [NAME] "{Name}" — LARGE elegant Korean serif font, champagne-gold metallic color. This is the biggest text element. 3. [Small decorative flourish line below the name] 4. [MAIN TITLE] "HAPPY BIRTHDAY" — large, bold serif typeface with a subtle ombre gradient from light pink to slightly darker mauve/rose. Second largest text. 5. [DATE] "{YYYY.MM.DD}" — clean, modern sans-serif font, high letter-spacing, smaller size, light gold or soft gray color. 6. [Small decorative flourish] 7. [MESSAGE] "{Message, e.g.: Shining OO, I support every moment of yours ♡}" — delicate handwritten-style script font, soft pink/mauve color, smallest text. === COLOR PALETTE === - Primary: soft cream, pale off-white - Secondary: muted lavender, pale petal pink, soft rose - Accents: champagne-gold metallic (for text, borders, ornaments) - NO saturated or neon colors. Everything is muted, airy, and romantic. === BACKGROUND & DECORATIVE ELEMENTS === - Smooth, dreamy gradient background — slightly warmer/deeper light in the center, diffusing to creamy-white at the edges. - BOKEH: fill the entire image with soft-focus circular bokeh highlights of varying sizes in white and light gold. Creates an ethereal, dreamlike quality. - FLOWERS (lower-left corner): cluster of soft-focus lavender and pink roses/hydrangeas. - FLOWERS (lower-right corner, near person): wispy white baby's breath (gypsophila). - PETALS: a few translucent floating pink flower petals scattered on the left side for depth. - BORDER: very thin, elegant gold-colored border framing the entire image. === OVERALL AESTHETIC === - Style: ethereal romantic, sophisticated, feminine, celebratory - Mood: warm, affectionate, wholesome — typical of K-POP idol birthday fan-made subway advertisements - Quality: professional graphic design level, clean layout, balanced composition between portrait and text - The final result must look like a REAL printed billboard ad you'd see in Gangnam Station or Hongdae Station. === CRITICAL RULES === - The person's face identity from the reference photo must be 100% preserved. - All Korean text must be spelled correctly with no typos. - Text must be crisp, legible, and beautifully typeset — not distorted or warped. - Maintain the horizontal wide billboard aspect ratio throughout.
