Sofia Black Velvet Gown Candlelight Stairs Prompt

Use my uploaded photo as face reference and keep my exact face, skin tone and features unchanged - no face swap, no beautification filter, natural skin texture. Create an ultra-realistic vertical 4:5 evening portrait of me on a grand candlelit palace staircase at night. I wear a black velvet off-shoulder evening gown with full fitted sleeves (opaque, floor-length), diamond stud earrings, my long dark hair in soft waves over one shoulder. I look over my shoulder at the camera with a confident soft smile, one hand resting on the carved marble railing. Dozens of warm candles in glass holders glow on the steps around me, deep shadows, cinematic romantic mood, realistic photography style, shot on 85mm lens, slight film grain, no text, no watermark.
