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.
