Bioluminescent guardian woman above a sunken abyssal city

The Abyssal Reliquary Subject: A 21-year-old Korean woman with a tall, lithe hourglass physique, matte-porcelain skin, and long, wavy reddish-brown hair. She is a "Deep-Sea Guardian" standing on the edge of a submerged underwater cliff. Her expression is calm and otherworldly, her eyes glowing with a faint, bioluminescent cyan light. Couture: She wears an "Ocean-Pressure" gown made of heavy, dark-teal velvet that has been "encrusted" with thousands of small, glowing blue barnacles and crystalline salt-structures. The bodice is a rigid, iridescent "Exoskeleton" carved from black pearl and polished abalone shell. The most striking feature is a massive, transparent "Water-Train" that flows from her waist; it is a shimmering, semi-solid gelatinous silk that contains a "micro-reef" of glowing jellyfish and tiny silver fish swimming inside the fabric itself. Her reddish-brown hair floats upward in the water-column, intertwined with glowing "Sea-Silk" threads that pulse like underwater lightning. Environment: The "Hadopelagic Trench," a vast, dark underwater canyon floor made of black volcanic sand. Scattered around her are the colossal, rusted remains of an ancient sunken city, now covered in glowing neon coral and swaying sea-fans. Above her, the "surface" of the ocean is a distant, shimmering silver mirror, with shafts of faint, distorted moonlight (God Rays) piercing through the deep-blue water. Lighting & Technical: High-contrast, cinematic underwater photography. The primary light is "Bioluminescent": a soft, pulsing neon-blue glow from the gown and the surrounding coral. The secondary light is a cold, ethereal "Moonlight" ray from above that highlights the iridescent textures of the abalone shell. Shot on a 35mm wide-angle lens to capture the scale of the sunken city. 16K resolution, hyper-realistic water caustic effects, sub-surface scattering on the skin and jellyfish-silk.
