Underground Cave City Comic QR Code for Posters

About this design

A huge cave city carved into sandstone walls, lit by a round skylight overhead, with small figures climbing a stone staircase toward a central tower. The finder squares are hidden in the dark window cavities of the stacked dwellings, and the black voids and pale carved facades carry the modules down the middle of the scene. Strong dark-against-cream contrast in the structure keeps the pattern legible against the soft teal haze. Pink shuttered openings and drifting green foliage add the only bright accents.
