Create an ultra-realistic casual outdoor fashion portrait closely based on the provided sample image, preserving its pose, body proportions, composition, framing, camera angle, staircase setting, railing placement, clothing style, facial expression, background blur, lighting, and natural photographic aesthetic. Show the user standing casually on an outdoor staircase beside a silver metal railing, with his body slightly angled toward the camera while looking naturally toward the side, holding a pair of eyeglasses loosely with both hands near his waist. Keep the same relaxed posture and candid fashion-photography feel as the reference. Dress the subject in a {Select Outfit, sage green half-zip sweater with light grey trousers, olive green sweatshirt with beige trousers, charcoal knit sweater with grey pants, cream pullover with light trousers, dark green casual sweater with black trousers}, with realistic knit/fabric texture, natural folds and a relaxed fit. Add {Select Eyewear, thin black-frame glasses held in hand, transparent-frame glasses held in hand, metal-frame glasses held in hand, classic rectangular glasses held in hand, no glasses} and {Select Hairstyle, naturally textured short hair, side-swept hair, modern quiff, slightly messy hair, classic short hairstyle}. Place the subject on a {Select Setting, outdoor staircase, modern building staircase, garden staircase, terrace staircase, residential staircase} with clean metal railings and lush green trees in the background, creating a soft natural bokeh. Use {Select Lighting, soft natural daylight, diffused morning light, warm afternoon sunlight, overcast daylight, cinematic natural light} with realistic skin tones, subtle shadows, detailed hair strands, authentic fabric texture, natural depth of field, softly blurred greenery, professional DSLR fashion photography, cinematic color grading, photorealistic 4K/8K quality, and a vertical 4:5 composition. MOST IMPORTANT: if the user uploads their own photo, preserve the user's exact facial identity 100% and keep the person visually similar to the uploaded photo. Do not change their apparent age, height, body weight, body size, body shape, facial structure, skin tone, hairline, beard/moustache, or natural physical proportions. Do not make the person taller, shorter, thinner, heavier, more muscular, younger, older, or artificially handsome. Preserve the exact face, eyes, eyebrows, nose, lips, jawline, facial proportions, and every recognizable identity characteristic from the uploaded photo. Only adapt the outfit, pose, environment, accessories, lighting and styling required to recreate the sample concept. The final image must look like the same real person naturally photographed in this exact type of staircase setting, with realistic hands, fingers, anatomy, clothing physics and railing geometry, no face morphing, body reshaping, excessive beautification, artificial muscles, distorted anatomy, extra fingers, extra limbs, cartoon, CGI, illustration, text, logo, or watermark.
