Минималистичный модный портрет на бетонной лестнице

A photorealistic full-body fashion portrait of [a young adult woman] leaning casually against a large pale concrete pillar in a modern minimalist interior. She has long dark brown wavy hair and an intentionally obscured face covered by a soft rectangular blur. Relaxed posture with shoulders against the pillar, barefoot with one leg crossed slightly in front of the other, both hands tucked into the front pockets of loose high-waisted wide-leg blue jeans, wearing [a plain white short-sleeve T-shirt]. The setting is [a contemporary concrete stairwell with polished dark floors], featuring a wide staircase rising on the right, angular concrete railings, and geometric window latticework near the top. Soft natural daylight casting long shadows across the floor and wall. Documentary editorial photography style, muted gray and blue color palette, subtle fabric folds, detailed denim texture, shallow depth of field, vertical composition. A subtle semi-transparent white watermark reading "[Alconia]" in the bottom-left corner.
