Create a highly realistic vertical 4:5 casual lifestyle portrait of a young adult man seated outdoors in a beautiful tree-lined urban setting. Use the uploaded photo as the visual identity reference; maintain consistent facial appearance, facial structure, eyes, eyebrows, nose, lips, jawline, skin tone, beard pattern, hairline, hairstyle characteristics, age, natural body proportions, and recognizable features. He leans slightly back with one arm resting naturally to the side, looking directly at the camera with a calm confident expression. Preserve thick dark textured hair with a slightly messy fringe and a full neatly shaped beard if present. Outfit: washed-black denim jacket with visible stitching, flap pockets, metal buttons, authentic worn texture, open over a clean white crew-neck T-shirt, dark blue jeans, narrow dark sunglasses with thin gold-tone frames. Early-autumn trees, warm late-afternoon sunlight, creamy bokeh, muted earthy tones, 85mm lens, shallow DOF, realistic skin, beard, denim, reflections, subtle grain, no text, logos, branding, or watermark. STRICT MASCULINE LOCK: preserve original grooming and facial hair, masculine styling only, no feminine elements, makeup, accessories or poses.
