Create a Cannes-level luxury fashion advertising poster for the original couture house named "IVORY BLOOM". It must be 100% location-based hyper-realistic editorial photography. Maintain a precise structural logic for the composition: a tall vertical poster with a soft close-up portrait of an adult female model positioned at its center. Her head is slightly tilted and turned, with a calm and distant editorial expression, wearing a high-neck ivory gown. A giant white peony blooms on one side of her head as the key visual balance. The entire image is set against a clean, warm butter-cream background with no environmental clutter. The final image must evoke the feeling of a coveted high-end fashion magazine cover: poetic, aristocratic, soft, cinematic, and unforgettable. Style parameters: hyper-realistic luxury fashion portrait photography, soft vintage editorial realism, top-tier couture beauty event, clean studio art background, no illustrations, no CGI feel, no plastic skin, no over-edited beauty filter effects. Core composition: a tight upper-body portrait with the model centered, her face and the flower occupying most of the frame, with gentle negative space reserved above solely for a large, elegant main title. No secondary text, body copy, footers, side notes, editorial paragraphs, or logo blocks. Only a single large, refined English title spanning the upper area is integrated as part of the composition. Suggested title: "IVORY BLOOM". Model styling: an adult female with naturally luminous pale skin, soft auburn or light brown fine hair framing her face loosely, delicate red-brown lips, a minimalist couture makeup look, and a high-neck ivory gown made of premium fabric with subtle sculptural pleats. Her body and face must remain elegant, natural, and anatomically correct. Floral styling: a giant white peony with dense layered petals and a rich golden center, placed beside the model’s head like a couture floral accessory. The flower must convey a fresh, luxurious, soft, and grand presence, serving as the primary visual symbol second only to the face. Lighting: soft diffused frontal light with subtle lateral shaping, delicate shadow transitions, softened cheekbone definition, glowing skin, and creamy highlights on the flower. The atmosphere should be transparent, warm, and luxurious, with no hard shadows, no muddy dark tones, or pitch-black areas. Skin and realism: only realistic human skin, visible fine pores, subtle facial micro-textures, faint vellus hairs, authentic lip texture, natural tone variations, slight translucency under the eyes, subtle warmth of capillaries, soft semi-matte finish, and genuine location-based details. No poreless skin, no waxy texture, no silicone-like appearance. Color strategy: a restrained palette including butter-cream, warm ivory, soft beige, petal white, soft auburn, and warm golden pink floral tones. Keep the image minimalist and harmonious, with the face and flower as the primary focal points. Artistic direction goals: model-first hierarchy, couture floral symbolism, elegant title-driven poster composition, high realism, flagship fashion impact, no clutter, no extra props, no duplicated brand identifiers, no watermarks. Negative prompts: duplicated luxury brand names, duplicated mastheads, duplicated paragraph text, any secondary text, body copy, footer text, repeated logos, watermarks, AI artifacts, CGI skin, plastic skin, waxy skin, poreless face, over-edited beauty filters, distorted facial anatomy, fake flower textures, low-resolution petals, muddy shadows, pitch-black patches, black smudges, cluttered composition, cheap fashion poster vibe, cartoon rendering.
