Cartoon Witch Halloween QR Code for Posters

About this design

A cartoon witch in a purple hat and layered cloak stands in the foreground, holding a small orb, with glowing jack-o'-lanterns, a potion bottle and a small cauldron around her. A skull and ghost wisp sit on a shelf above. The wavy pale blue wall behind her is full of dark rounded cutouts, and these hold the dark modules of the QR code, while the stone blocks, pumpkins and shelf pots help hide the finder squares. Light cyan shapes against the deep navy keep the pattern clear, and the orange pumpkin glow adds a warm accent.
