Polluted Factory Skyline Vector QR Code for Stickers

About this design

A factory skyline with smokestacks and tall city towers sits under heavy teal smoke clouds and a round orange sun. Two square factory blocks with dark and rust circles at their centers disguise the finder squares, while the pixelated central tower and the gear-shaped smoke puffs carry the modules. Navy shapes against pale blue and amber keep the dark and light pattern clear, and the detail is spread evenly across the round sticker shape. Dark floating rubble beneath the city anchors the composition.
