A river of electric ultramarine velvet winding in an S-curve through rounded, close-cropped grass banks, the fabric bunching and rucking into long draped folds that follow the current the way water would. A man in a crisp white suit, white shirt and black shoes stands mid-river holding a wide wooden push-broom, bent forward at the waist, sweeping the velvet flat and leaving a smoothed pale track behind the brush head. Clear flat cyan sky, no clouds, no horizon detail. Elevated three-quarter camera angle looking down the length of the river, wide lens, everything in focus. Hard midday sun from the upper right so the velvet pile shifts between deep navy in the folds and bright blue where the nap catches light, and the grass banks show a crisp cut edge where the turf meets the fabric. Editorial set-build realism, real fabric weight, faint studio dust and fine grain.
