Underwater scene, mysterious dark ocean, glowing bioluminescent plants, eerie fog, a majestic underwater castle in the distance, a pale-skinned vampire woman, long curly hair flowing like seaweed, piercing green eyes, crimson lips, ornate Victorian-style dress with tattered edges, torn fishnet stockings, seaweed-covered boots, dramatic flowing cape, brooding expression, surrounded by swirling schools of small fish, subtle shimmering scales, moonlight filtering down from above, hauntingly beautiful ambient lighting.
