Celestial Bride on Starlit Beach

Create a luminous fantasy seascape illustration in a dreamy anime-inspired painterly style. Use a vertical {argument name="aspect ratio" default="2:3"} canvas showing a vast turquoise ocean on the left and a bright white sandy beach on the right, with the shoreline curving diagonally into the distance. A solitary {argument name="character" default="young woman with very long white hair"} stands near the waterline in the lower-right third, seen mostly from behind in dark silhouette against the glare, wearing a flowing {argument name="dress color and style" default="white bridal gown with a long translucent train"} that trails across the glowing sand and ripples in the sea breeze. Above her, create an enormous celestial sky: deep sapphire at the top fading to cyan near the horizon, filled with countless stars, a soft Milky Way band, and one bright crescent moon in the upper-left. Add towering white cumulus clouds on both sides, textured with thick impasto brushstrokes and cool lavender-blue shadows. The ocean should be crystal clear, sparkling with sunlike reflections and visible shallow-water patterns; include subtle lens flare and rainbow glints near the foreground. Make the scene radiant, ethereal, high detail, wide-angle, serene, romantic, and magical, with no text, no border, and no extra characters. Emphasize the contrast between the starry night sky and the bright daylight-like beach, as if moonlight and starlight are illuminating everything.
