Mostro Marino Colossale sopra un Sub sul Fondale Oceanico Illuminato dal Sole

A dramatic fantasy scene in the style of Frank Frazetta, depicting a colossal prehistoric reptilian leviathan with shimmering greenish scales and an enormous, gaping maw filled with jagged teeth, gliding majestically above a rugged, rocky and tan sandy ocean floor. A terrified deep sea diver stands in awe looking at the leviathan. Vibrant clusters of coral in reds, purples, and oranges dot the landscape, while schools of iridescent fish swirl around the leviathan, adding movement and life. The water is slightly murky, with beams of sunlight piercing through the surface, creating striking patterns of light diffraction on the sand below. In the foreground, a deep sea diver in a classic suit stands transfixed in awe, dwarfed by the immense creature as it approaches, capturing a sense of wonder and scale. The overall mood is epic and mysterious, with rich, saturated colors and dynamic lighting reminiscent of Frazetta's iconic fantasy artwork.
