Ultra-realistic high fashion studio portrait seated

Create an ultra-realistic full-body high-fashion studio portrait using the reference subject, male or female, preserving exact facial identity, structure, proportions, natural skin texture, pores, and recognizable features. Seated sideways on a sleek matte-black chair in a composed posture, mid-thigh-to-head framing with head and feet fully visible and balanced negative space. Wearing a tailored black pinstripe blazer over a matte-black shirt with subtle cuffs, straight-fit black trousers, polished black Chelsea boots, and thin transparent black-framed aviator glasses. One hand adjusts the opposite sleeve cuff; body slightly sideways, head turned away, gaze off-frame, neutral calm introspective expression. Deep matte-black seamless background with symmetrical embossed Baroque ornaments. Soft diffused front-left key light, gentle shadows and subtle rim separation. Fine lens-bloom/micro oil-film diffusion softly reduces edges while preserving facial and fabric detail. Eye-level 85mm look, shallow DOF, crisp subject, subdued background, deep blacks, controlled contrast, cinematic grading, 4K–8K editorial finish. 4:5 aspect ratio.
