Create an elegant, ultra-realistic vertical birthday portrait poster featuring the same young woman in three beautifully arranged portrait poses, closely matching the reference image's composition, portrait placement, soft floral aesthetic, clothing style, background, typography area, and overall premium birthday-poster design. The largest portrait should appear in the upper-left area, showing the woman from the chest upward with long flowing hair, a gentle natural smile, and her body slightly turned while looking toward the camera. A second medium-sized portrait should appear on the upper-right side, showing the same woman standing naturally with one hand gently touching her hair, while a smaller third portrait should appear in the lower-center area with the woman resting her chin softly on one hand and smiling toward the camera. All three portraits must use the same exact person and facial identity. Dress her in a {Select Outfit, olive green embroidered saree, sage green saree, pastel green saree, olive green lehenga, sage green traditional suit, floral green dress} with delicate embroidery and elegant traditional detailing, styled with {Select Hairstyle, long open wavy hair, loose curls, soft side-parted waves, straight open hair, voluminous natural waves} and {Select Jewelry, small traditional earrings, jhumka earrings, delicate gold earrings, pearl earrings, minimal festive jewelry}. Use {Select Background, soft cream floral background, ivory watercolor background, white botanical background, pastel beige background, elegant floral paper texture} with subtle green botanical leaves, soft watercolor floral splashes, delicate foliage around the portraits, light paper texture, gentle faded decorative elements, and a clean premium feminine aesthetic. Use {Select Theme Color, sage green, olive green, pastel green, dusty rose, lavender, beige} as the dominant accent color while maintaining a soft cream-and-white base. Add elegant birthday typography in the lower portion reading “Happy Birthday” in sophisticated handwritten calligraphy, with a smaller customizable birthday message underneath: “May your special day be filled with happiness, beautiful memories, and endless smiles.” Keep the typography clean, readable, refined, and naturally integrated into the poster without overlapping the portraits. Use soft diffused studio lighting, realistic skin texture, detailed hair strands, authentic fabric and embroidery, natural facial expressions, subtle shadows, delicate background blending, premium portrait photography, sophisticated editorial design, photorealistic 8K quality, and a vertical 4:5 composition. If the user uploads a photo, preserve the user's face 100% exactly as provided, including facial structure, eyes, eyebrows, nose, lips, jawline, skin tone, hairline, facial proportions, and all recognizable identity characteristics; do not beautify, reshape, redesign, retouch, age, de-age, or reinterpret the face, and ensure all three portraits contain the exact same facial identity. Keep the final result elegant, feminine, soft, festive, premium, and photorealistic, with no distorted face, malformed hands, extra fingers, duplicate facial features, inconsistent identity, artificial skin, cartoon, CGI, illustration, unwanted text, logo, or watermark.
