Underwater Angel Fantasy Illustration

Create a highly detailed, polished anime fantasy illustration of a serene underwater angel girl resting against an ancient curved stone structure. The scene shows one young female angel with {argument name="hair color" default="long flowing golden-blonde hair"}, soft amber eyes, delicate pale skin, and a calm melancholic expression, wearing a translucent layered {argument name="dress style" default="white lace dress with ruffled organza and floral details"}. She has exactly two large white feathered wings spread behind her, illuminated by sunlight from the water surface above. Her body floats diagonally from lower left to upper right, bare legs extended, one arm gently hugging the mossy stone arch. The setting is a luminous deep-blue underwater ruin with clear water, bubbles, caustic light rays, drifting fabric, and small marine growth. Include exactly one large curved ancient stone arch or boat-like ruin covered in dark teal moss, coral, tiny white flowers, and ornate spiral carvings. Add many floating white feathers of different sizes around her, with three prominent blurred foreground feathers near the lower right and right edge, plus smaller sharp feathers near the wings. The composition should be vertical, cinematic, and immersive, with the bright sunburst centered near the top, rippling water surface overhead, intense turquoise-to-cobalt blue background, and soft volumetric god rays. Use intricate feather rendering, realistic underwater lighting, sparkling highlights, clean detail retention, no noise, no ink splatter, no text, no watermark, no frame. Style: premium Japanese anime key visual, ethereal fantasy, painterly but crisp, delicate facial features, highly refined fabric transparency, romantic and dreamlike atmosphere. Use {argument name="aspect ratio" default="3:4 vertical"}.
