Cinematic film still, dark baroque fantasy style inspired by Guillermo del Toro. A lone solitary figure of a man viewed from behind, wearing rough ancient woven robes soaked by rain, standing on a jagged black rock jetty. Facing him, emerging from a pitch-black stormy ocean, is the colossal biblical Leviathan, manifesting as a giant abyssal serpent and deep-sea dragon hybrid. This ocean monster has a massive, sinuous body rising high above the waves like a tower. Its hide is absolute impact black, a tectonic mass of oily obsidian and basalt that absorbs light. The creature is covered in armor of gleaming black draconic scales like hardened tar. It stares at the small man with multiple sad ancient eyes. Bioluminescent deep cracks glow with faint amber magma light on its neck. Dramatic chiaroscuro, stormy night, heavy rain, gothic atmosphere, rich tactile textures, 35mm film grain, practical effects aesthetic.
