Generate Marble Chessboard Fashion Portraits

Reference contract: Use the uploaded image as the identity anchor for the subject. Preserve the subject's recognizable likeness, face shape, eye spacing, nose shape, lip shape, skin tone and undertone, hairline, age cues, body proportions, natural expression, and gaze. Change only the wardrobe, pose, setting, lighting, and styling. Create a photorealistic portrait of the subject standing on a giant marble chessboard as a modern life-size chess piece, 4:5 vertical aspect ratio. The subject is full-body visible, facing camera, wearing sculptural monochrome fashion inspired by a chess queen or king silhouette: a long structured coat, high clean collar, subtle geometric tailoring, dark trousers, and polished boots. The look should feel editorial and wearable, not cosplay. Oversized marble chess pieces stand behind and beside the subject at human scale. Composition: full-body centered portrait, feet included, low marble chessboard perspective with strong black-and-white floor geometry leading toward the subject. Lighting: soft overhead studio light with subtle side rim light, clean reflections on polished marble, realistic shadows beneath the subject and chess pieces. Camera and optics: Hasselblad X2D 100C, 50mm lens, f/3.5 aperture, 1/200s shutter speed, ISO 100. The subject must look physically present on the board, with matching scale, contact shadows, fabric texture, marble reflections, realistic skin detail, and consistent lighting across face, neck, hands, clothing, and surrounding pieces. Text: no in-image text. Constraints: no watermark, no brand logos, no crown covering the face, no extra people, no duplicate subject, no warped anatomy, natural hands, no plastic skin, no pasted-on face, no cutout edges, no mismatched face and neck lighting, no floating body effect, no fantasy glow.
