Art style: Cinematic Realistic.
Full-length view, the entire figure visible from head to fluked tail, held upright and vertical, correctly oriented and centered — an immense ancient abyssal Leviathan. Its serpentine body stretches enormous, sheathed in slate-grey and bruise-black scales crusted with barnacles, pale scars, and clinging tubeworms. The elongated skull bears sunken bioluminescent eyes glowing faint sickly green, a wide jaw lined with irregular translucent fangs, and trailing whisker-like feelers. Ribbed flanks show ancient wounds; tattered dorsal fins and long pectoral fins ripple like torn sails, tipped with hooked claws. A muscular tail ends in a broad crescent fluke. It hovers in crushing black water, faint silt drifting, marine snow falling, dim shafts of distant light from far above. Vast, cold, predatory, unhurried menace fills the frame.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cinematic Realistic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cinematic Realistic". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Cinematic Realistic" idiom, not in any other medium.
