오로라 빛으로 된 스펙트럴 인어가 우주 하늘을 헤엄치다

Masterpiece. Best quality. Ultra detailed. Beautiful composition. Cinematic. Epic. Dramatic. Attention-grabbing. A spectral mermaid, her form composed of shimmering aurora borealis, swims through a sky filled with constellations. She trails nebulae behind her like a silken gown, her tail fin splitting into stardust. The scene evokes a cosmic, ethereal mystery. Masterfully rendered in a style blending celestial fantasy art with the dramatic, high-contrast lighting of baroque portraiture, and elements of cinematic space opera.
