Sunken Citadel Siren Abyssal Throne

A haunting dark fantasy portrait of a sunken citadel siren in her mid-twenties, featuring iridescent blue-black scales along her neck and shoulders, long flowing dark teal hair floating weightlessly in deep ocean water, shimmering dark eyes, and delicate fin-like ears, wearing a tunic crafted from dark pearl chains, seaweed silk, and black coral armor, seated upon a massive throne carved from giant leviathan sea monster bones inside an underwater flooded gothic cathedral, surrounded by swimming glowing jellyfish, ancient sunken ship debris, submerged stone gargoyles, and sunbeams piercing down through murky deep blue ocean water, illuminated by bioluminescent aquatic flora and flickering cold sunlight rays casting caustics water ripples across her scale skin and bone throne, holding a sea-glass triton artifact, captured in an epic wide-shot composition, 35mm lens, f/2.2 aperture, aquatic cinematic color grading with deep oceanic blues, dark teals, and luminous turquoise highlights, dark surreal fantasy aesthetic.
