A young boy sitting in train window inside an Indian Railways train coach.

"A candid lifestyle portrait of a young man with thick, curly dark brown hair and a full, neatly trimmed black beard and mustache, looking at the camera with a calm, slightly smirking expression. His head tilts to the side while one fist rests under his chin. He sits by the window inside an Indian Railways train coach, wearing a black and white color-block windbreaker jacket with a white sleeve panel, a visible sports-brand logo and lettering down the front, and a black string bracelet on his wrist. Behind him are the train's cream-grey interior walls, three wall-mounted power sockets with a small brass seat-number plate, a rounded window with a bright, hazy outdoor landscape of trees rushing past, and teal-blue padded seating on the right. A plastic water bottle and a small can sit on the window ledge, with white pillows and bedding in the foreground. Warm golden-hour sunlight streams in from the side, casting soft highlights on his face and jacket, with glowing light on the wall behind him. Warm, slightly overexposed travel-diary mood, natural skin texture, shallow depth of field, shot on a smartphone, vertical 3:4 aspect ratio, sharp focus on the face." 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.
