The brief was river-flow digital-fusion for rural clean-water access — how a purifier unit reads beside classical pond-vessel grammar without turning the canvas into a product brochure or defaulting to chauk-central marriage geometry. River-flow stacks bank scene above wavy water bands the way fishing-net and pond-vessel classical subjects do; the purifier rectangle anchors the hero bank like a village infrastructure monument. What we refused: tarpa dance ring, multicolor filter labels, perspective depth on machine, photoreal pipe fittings. What we kept legible: three-column filter window, gauge circle, woman at main tap, child at side pipe, matka circles, boat with oar and stacked pots, fish in flow lines. Light density (~43% fill) lets ochre breathe between bank and river registers.
