Cinematic Underwater Astronaut Portrait

: A cinematic, photorealistic medium shot of a young man with distinct facial features matching the provided reference image, wearing a detailed white astronaut suit with a collar ring and chest control module. He is submerged in deep, dark-blue ocean water filled with glowing, translucent jellyfish floating around him. He is gently pointing upward with his index finger toward a large, luminous jellyfish floating close by, his expression full of wonder and curiosity. Volumetric deep-sea lighting filters down from above, illuminating fine bubbles, floating particulates, and the ethereal glow of the jellyfish, creating a surreal, magical deep-water atmosphere. Hyper-detailed skin texture, dramatic rim lighting on the hair and shoulders, 8k resolution, photorealistic cinematic composition. 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.
