How to use this prompt

The brief is cozy-spooky, not horror, so the negative bans "gore" and "scary faces" and the prompt keeps the mood "warm orange and deep purple" — that palette is the friendly side of Halloween. A garland of "small pumpkins" is used rather than a stated count, because counting pumpkins invites the model to drop some; a garland reads as a continuous strand. Paper bats on the wall are a flat-design-friendly motif that adds the spooky note without frightening. Keep the shapes clean and flat with no text — a mantel scene with a sign would invite garbled lettering. A 3:2 frame fits the mantel's horizontal line.

Variations to try

  • Night version — darker palette with the candles lit
  • Entryway — the same styling on a console table by a door
