Create a photorealistic extreme close-up underwater portrait based on the provided reference person: a young South Asian man with medium-brown skin, short side-swept black hair, thick eyebrows, brown eyes, and a neatly trimmed full beard and moustache. He has just entered a clear swimming pool and is calmly suspended underwater, face filling the frame at a slight three-quarter angle, eyes open with a serene relaxed expression. Preserve his recognizable facial features. Tiny air bubbles drift around his hairline and cheeks, with softly rippling pool-surface reflections and luminous caustic patterns across his skin. The water is crystal clear turquoise-blue, shallow depth of field, cinematic natural sunlight from above, weightless ethereal mood, no distress or urgency.
