A close-up of a fully bloomed lily with a deep midnight blue gradation is placed at the center. Tiny silver particles are scattered around the edges of the petals, creating a velvety, smooth texture that coexists with the transparency of water droplets. The composition is a portrait angle that captures the flower vertically, focusing on the delicate details of the stamens and pistils. The background evokes a fantastical underwater world, with a blend of dark blue and purple, and the light is a mysterious spotlight that highlights only the outline of the lily. The digital art style has a tranquil, surreal atmosphere, like a single flower blooming in a deep-sea palace.
