Glamorous Backless Gown Portrait

Create a vertical high-fashion editorial portrait of a glamorous woman with {argument name="hair color" default="long auburn hair"} standing in a three-quarter back pose, looking over her shoulder, with her face intentionally covered by a flat opaque square censor block in a warm brown skin-tone color. She wears a dramatic {argument name="dress color" default="black"} evening gown with an open back, halter-style neckline, gathered draping at the waist and hip, and metallic {argument name="metallic accent color" default="gold"} fabric accents wrapping across the bodice and waist. Her hair flows to the left as if moved by a light breeze, and she has elegant jewelry including one dangling earring and one ring. Place her in front of a large abstract textured painting background with thick impasto brush strokes, palette-knife relief, and warm autumnal colors: ochre, bronze, gold, rust red, burnt orange, cream, taupe, and smoky brown. Use warm directional studio lighting from the upper left, soft shadows, realistic skin texture, glossy fabric highlights, and a luxurious gallery atmosphere. Frame from mid-thigh upward, centered slightly right, with the open back and silhouette emphasized. Photorealistic fashion photography, 4:5 vertical aspect ratio, rich contrast, painterly background, no visible text, no watermark.
