Photorealistic editorial portrait of a young South Indian man

Photorealistic editorial portrait of a young South Indian man sitting casually on a dark rocky surface, viewed from a dramatic low-angle perspective. He has natural curly black hair, short beard, warm realistic skin texture and a relaxed confident expression, looking directly at camera. One arm rests behind his head while the other arm is raised with a relaxed fist. He wears a dark navy-blue overshirt over a plain white T-shirt, light-wash loose jeans and clean white sneakers. His legs are spread toward the camera, creating strong foreground perspective, with the sneaker soles clearly visible. Bright blue sky filled with soft white cumulus clouds behind him, natural daylight, crisp realistic shadows, vibrant but natural colors. Preserve the exact pose, framing, perspective, clothing, composition and sky from the reference. No anime, no illustration, no cartoon features. Strict 4:5 Instagram post, 1080x1350. 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.
