Prompt de imagem
Create one vertical 736 by 1308 photographic image, approximately 9:16, looking almost straight down into clear shallow blue water. Fill the entire canvas with the water surface and dark smooth stones beneath it. There is no visible bank, container, sky, horizon or bottom edge of a pool. Keep a single pink hibiscus blossom centered near x50 percent and y50 percent, spanning approximately x35 to 65 percent and y42 to 59 percent. Preserve the nearly balanced water margins above and below it. Preserve extensive water around it on every side.
The hibiscus has five broad irregular petals, softly ruffled and slightly translucent, in dusty rose and muted salmon pink. Fine darker veins radiate outward through the petals. Its center is a dark burgundy throat edged with a small warm yellow zone. A short central stamen rises from the throat. No stem, leaf or second flower is visible. The blossom rests face upward, with enough natural asymmetry to feel like a real fallen flower rather than a perfectly arranged icon.
Render the water as many interacting ripples with finely defined refraction. Dark navy and blue gray stones form soft rounded shapes below, distorted through the surface. Bright white and pale cyan caustic lines form an irregular connected web across the whole image. Include a few concentrated pinpoints of reflected sun near the lower edge, with darker calm pockets between them. Keep the water richly varied rather than repeating one ripple pattern.
Use crisp natural daylight and a cool sapphire, cobalt and turquoise palette, with the flower as the only substantial warm accent. Fine photographic grain and natural microcontrast; preserve the delicate petal texture against the stronger reflective water. No oversized bloom, multiple flowers, hands, decorative text, watermark, border or interface.
