Post Apocalyptic Ruined City 3D Building QR Code for Posters

About this design

A collapsed city block of crumbling concrete towers, gaping holes and twisted rusted beams rises over a debris-covered ground under a teal sky. The finder squares are hidden in the broken building masses and the dark window openings, while the modules run through the cracked wall textures, shadowed cavities and scattered planks. Strong dark and light contrast between voids and pale concrete keeps the pattern legible across the structure. A distant industrial megastructure arch adds depth behind the ruins.
