Elegant young woman seated on an ornate gold swing

Elegant young woman seated on an ornate gold swing in a grand opulent hall, wearing a floor‑length royal blue gown with long sleeves and a full flowing skirt, matching blue heels, long straight dark hair, delicate statement earrings and subtle makeup, poised serene expression, one hand resting on her lap and the other holding a decorative swing chain. Swing wrapped in warm white fairy lights, soft glowing chandeliers and arched architecture blurred into a creamy bokeh background, polished marble floor with reflective sheen, symmetrical centered composition, rich golden accents contrasting vivid cobalt fabric. Soft cinematic warm lighting, gentle rim and key light on the face, shallow depth of field, crisp texture on fabric and metalwork, photorealistic high resolution portrait, cinematic color grading, calm elegant mood, low eye-level camera angle, slight vignette for intimacy. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
