Nacreous Clouds Over Sapporo Twilight

Pearlescent nacreous clouds drift across a dark polar night sky above the Sapporo horizon. Iridescent bands of pale green and soft violet shimmer within the thin stratospheric layer, glowing against the deep indigo backdrop. Below, low-hanging cloud banks obscure the cityscape, their gray undersides reflecting the faint twilight glow. A wet asphalt surface in the foreground mirrors the cloud colors, doubling the iridescence in a slick, dark sheet. The composition remains stark and minimalist, showing the vast vertical distance between the ground and the glowing stratospheric bands. Sharp edges of the cloud layers contrast with the smooth, oily reflection on the pavement below.
