Here’s a detailed, ready-to-use prompt based on the photo:

A realistic portrait of a young South Asian man in his mid-20s sitting outdoors in a grassy hillside. He has thick, voluminous, curly black hair with natural volume and some loose curls falling over his forehead. He has a well-groomed short beard and mustache, sharp facial features, warm brown skin tone, and a calm, slightly serious expression while looking off to the side. He is wearing a dark charcoal-grey wool overcoat with a high collar over a plain black crew-neck t-shirt. He is seated among dry, tall brownish grass in the foreground. The background shows soft, misty mountain ranges under an overcast, cloudy sky with cool, diffused natural lighting. Cinematic photography style, shallow depth of field, sharp focus on the face, muted earthy tones, moody and atmospheric feel, high detail, photorealistic. 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.
