The background is an old wooden porch at night strung with fairy lights, carved pumpkins on the steps, light mist and warm orange candlelight.

Tips
Name the costume pieces precisely: “black wide-brimmed pointed hat, purple velvet cape” beats “witch costume”.
Warm candlelight and string lights look festive; cold moonlight and fog look spooky. Pick one.
For posters, put the exact date, time and venue in quotes; GPT Image 2 VIP and Nano Banana Pro both got every line right in our sample.
Gore and realistic violence are refused by most models; stylized spooky works fine.
