Halloween Potion Room Cartoon QR Code for Event Invitations

About this design

A cartoon potion room full of glowing jack-o'-lanterns, wooden shelves of bottles and herbs, and a bubbling pot at the center, all lit by a cyan arch with bat silhouettes. Pumpkins, hanging lanterns and the stacked shelf units hide the finder squares, while dark floating orbs, bats and small bottles carry the modules across the scene. Strong contrast between the dark brown shapes and the bright teal glow keeps the pattern readable. The pumpkins in the foreground add a warm orange accent against the cool background.
