Underwater Crystal Cave Fantasy QR Code for Stickers

About this design

A hidden underwater cave opens onto a seabed of pink coral, lavender sea plants and glowing crystals, all inside a round sticker shape. Square stone frames set into the cave wall and a carved block near the floor disguise the finder squares. Pale cyan crystal formations hang from the ceiling and form the light modules against dark purple rock. Strong contrast between the luminous teal shapes and the deep shadowed background keeps the pattern legible, while the coral and plants stay in the lower area as decoration.
