Ultra realistic cinematic portrait of a fashionable girl

Full-body photograph of a fashionable young woman posing in a modern indoor staircase with concrete-like tiled walls. She wears a vibrant red faux leather jacket open, a black crop top, high-waisted wide-leg charcoal-grey washed jeans, and white sneakers. She has long dark hair, wearing round metal sunglasses, and stands confidently, pulling the edges of her jacket with both hands, looking towards the camera with a slight smile. The background features a metal handrail and dramatic, defined shadows cast by natural light. 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.
