Line art only, clean contours on flat ground, Retro Futurism forms: villagers hauling long planks and coils of rope across a swollen river, atomic-age curved pylons and riveted trusses half-built toward the far bank. Muted palette of slate blue, dusty ochre, moss grey, faded brick. Single hard light casts dramatic shadows; spiral particle swirls of pale dust stream upward as clouds split.
