「DON'T LOOK BEHIND U :)」は、暗いゴシックホラー調のハロウィンパーティーポスターです。血のように滴るオレンジの3D大文字が、ひび割れた古い鏡に映る影の人物の上に配置され、火の灯ったろうそく、本の上のドクロ、小さなカボチャ、蜘蛛の巣が周りを飾り、下に日付が入ります。見出し、「HALLOWEEN PARTY」の文字、日時を差し替えて自分のポスターを作れます。

Create a finished vertical Halloween party sign, 3:4, with professional cinematic key-art composition. Render these exact lines, with no extra text: headline “DON'T LOOK BEHIND U :)”; supporting line “HALLOWEEN PARTY”; details “OCTOBER 31 · 8 PM”. Make the headline the dominant tier, split into two centered lines: “DON'T LOOK” / “BEHIND U :)”. Use broad, weighty classical serif letterforms with generous width, strong thick-thin contrast, deeply chiseled stone structure, and sharply cut V-shaped wedge serifs. Coat the carved forms in saturated molten orange enamel; preserve fine stone-cut facets beneath the glossy surface. Orange enamel gathers and hangs in distinct rounded drips from the lower edges of the glyphs, without obscuring any character. The headline must remain clearly readable. Set the supporting line small and widely tracked above the title; place the date and time as a compact, legible footer. Behind and below the title, show a tall antique mirror with a cracked dark frame; its glass reflects only a vague human-shaped shadow standing behind the viewer. Give the mirror its own visible area, separate from the text. Place fine cobwebs in all four corners, with strands catching orange rim light. Use a deep purple-to-black background, controlled shadow depth, cinematic volumetric shafts, strong directional key light across the carved letters, a restrained horizontal anamorphic lens flare, shallow edge vignette, and fine film grain. Photorealistic 3D rendering, crisp foreground/background separation, high contrast, rich tonal range, no extra symbols, no additional wording, no cropped letters.
