A highly detailed, cinematic-style underwater scene where the camera spirals downward into the dark ocean. Bioluminescent creatures scatter in glowing streaks of blue and green as the depths grow darker. Suddenly, a colossal, dragon-like silhouette looms in the abyss, shrouded in shadow and ancient mystery. Its massive form is barely visible, coiling through the murky water, with faint glowing patterns pulsing along its scaled hide. The deep-sea currents swirl ominously, creating an eerie and otherworldly atmosphere. The composition is dynamic, emphasizing the vast, unknown depths and the overwhelming presence of the hidden leviathan. Dramatic lighting enhances the mysterious and foreboding tone.
