Carpes koi nageant sous les feuilles de lotus, vue sous-marine

A fantastical yet photorealistic natural landscape merging highly detailed digital environment illustration with 3D/CG, in an ultra-wide-angle upward view close to the floor of a clear lotus pond. The lower third features several red-and-white and orange-gold koi carp as the main visual, swimming among layered dark-green lotus leaves; numerous slender long stems extend upward from all sides, the leaves showing clear radial veins, thin translucent edges, and natural occlusion. In the upper-middle, the rippling water surface shows blue-green refraction and silvery-white ripples, through which a highly saturated azure sky, fluffy white clouds, and a dazzling sun at the upper left are visible. Strong backlight pierces through the water, leaf edges glow, and the pond floor retains deep blue-green shadows; the warm colors of the koi form a few visual focal points; the foreground is sharp while the mid-to-far ground has slight water scattering, with a few bubbles, translucent fins, and fine scales added, creating a transparent, lively, and immersive space.
