Pastel Blue Birthday Celebration Portrait

Use the uploaded photo as the ONLY facial reference with strict identity preservation. Maintain the subject’s exact facial structure, proportions, eye shape, eyebrows, nose, lips, jawline, skin tone, and unique features with zero beautification or identity drift. Create a cheerful, brightly lit, pastel-themed birthday portrait with a polished K-pop fan-event aesthetic. The subject stands centered, facing the camera directly, smiling warmly with teeth visible, holding a round birthday cake with both hands at chest level. Shoulders are relaxed, posture natural and elegant, and the pose, hand placement, camera angle, and framing must remain consistent. The subject wears a modest light-blue princess-style dress with a fitted bodice and off-shoulder design, featuring sheer ruffled tulle sleeves. A matching light-blue beret with a small white two-trapezoid logo sits neatly on the head. Accessories include a pearl necklace and small dangling earrings. Hair is long, softly wavy, and neatly styled over the shoulders. The cake is white with smooth frosting, “Happy Birthday” written in blue cursive icing, pastel pink and yellow decorations, and three lit candles. The background is a solid powder-blue wall with large puffy pink “HAPPY BIRTHDAY” letters, pastel blue and pink balloons, and white-and-blue triangular bunting. Cute fan-style cartoon cutouts and extra pastel decorations add a playful celebration vibe. Lighting is soft, high-key, and evenly diffused with minimal shadows, producing clean, natural skin texture. Colors are airy and pastel, with sharp focus, gentle depth of field, and a premium studio finish.
