A dark, eerie cemetery scene with old, weathered tombstones scattered across the fog-covered ground. The thick fog swirls around the gravestones, creating a haunting, mysterious atmosphere. The sky is dark, with only a faint glow, adding to the ominous mood. The text "happy halloween" is prominently displayed, taking up 1/4 of the image, in a spooky, gothic font that complements the eerie setting. The overall design is chilling and atmospheric, with a strong focus on the dark, foreboding cemetery. Vector graphic, monochrome with subtle dark tones, Halloween theme --ar 16:9 --q 2 --s 750
