Casual Portrait in a Modern Corridor

A realistic full-body portrait of a young South Asian man standing casually in a modern indoor corridor, wearing a loose off-white textured button-up shirt with dark buttons and light blue relaxed-fit jeans. He has thick, slightly messy black hair, light stubble, and a serious, confident expression. He is standing at a low-angle camera perspective, looking slightly down toward the camera. Modern beige and grey tiled walls with dark marble accent strips, doorway in the background, soft natural indoor lighting, subtle warm tones, realistic skin texture, detailed fabric, cinematic photography, shallow depth of field, photorealistic, high detail, 4K. 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.
