Underwater Diving Tower Portal

Create a vertical cinematic underwater surreal photograph of subject standing on the ocean floor, seen from a low wide angle in murky blue-green water. The tower is tall, weathered, algae-stained, and monolithic, leaning slightly in perspective, with exactly 5 visible protruding structures: 1 long top diving board with a lone human diver standing at its very end, 1 small upper side platform, 1 middle platform with a thin railing, 1 lower platform, and 1 wide base-level platform with a ladder descending beside it. The diver is tiny compared with the structure, wearing swim trunks or a minimal diving suit, posed upright and contemplative as if about to dive. In the foreground, cut into the sandy seabed, place a large square shaft or portal glowing with warm golden-yellow light, as though it leads to another deeper ocean or impossible depth below; the square opening should have rough vertical concrete or rock walls and bright luminous water inside. Include exactly 24 small fish silhouettes scattered across the mid-right water column in loose groups, plus a few tiny dark particles and bubbles suspended throughout. The water surface is visible far above as a pale rippled ceiling with diffused sunlight, while the background fades into deep teal haze. Use mood atmosphere, realistic underwater photography, soft volumetric light rays, suspended sediment, muted colors, high detail, no text, no logo, no watermark. Emphasize the impossible concept: the highest diving board in the world located at the bottom of the ocean, with even more depth glowing beneath it.
