Full-body photorealistic portrait of a stylish young man

Full-body photorealistic portrait of a stylish young man walking toward the camera on an urban tree-lined path during golden hour, casual confident pose with one hand in his pocket and the other relaxed by his side, wearing a deep magenta button-up shirt left open over a clean white t-shirt, slim black jeans, white sneakers and a black wristwatch, dark sunglasses and neatly groomed beard and hair. Soft warm backlighting from the setting sun, strong shallow depth of field with creamy bokeh, background of golden autumn leaves and cool blue-toned shadows, blurred pedestrians for depth. Cinematic color grading with warm highlights and cool midtones, high resolution, sharp subject detail, natural skin tones, slight low-angle perspective, 50mm equivalent, f/1.8, realistic textures, subtle film grain, vertical 2:3 composition. 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.
