Photorealistic daytime street portrait of a young man

Photorealistic daytime street portrait of a young man standing on vivid green artificial turf in a modern city plaza, full-body composition, centered foreground, relaxed pose with hands in pockets, wearing a fitted black button-up shirt and dark jeans, short brown hair, light stubble and clear rectangular glasses, calm confident expression, natural skin tones, soft sunlight casting crisp shadows. Midground features landscaped grassy mounds, palm trees, a road with bollards and cars, and a striking futuristic torus-shaped metallic building covered in large flowing Arabic calligraphy, highly reflective chrome surface catching blue sky and surrounding skyscrapers. Background shows tall glass-and-steel towers under a clear blue sky, gentle lens flare, high dynamic range, sharp detail, rich saturated colors, subtle bokeh on distant buildings, cinematic composition, 35mm perspective, shallow-to-medium depth of field, realistic textures and natural contrast. 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.
