산호초의 고대 돌 위에 쉬는 몽환적인 인어

An ethereal mermaid with bioluminescent scales and flowing, seaweed-like hair, sits on a moss-covered ancient stone in a deep, underwater enchanted coral reef. Moonlight filters through the waters above, casting ethereal beams on the mystical flora and fauna. The scene evokes a sense of melancholy beauty, captured in a photorealistic style with a touch of dark fantasy horror.
