「BLOOD MOON BASH」は、暗くて恐ろしい雰囲気のゴシック調ハロウィンパーティー用フライヤーです。赤く光る月の下に血が滴る赤いブラックレターの文字を置き、その下に黒いろうそくと血の入った杯を配して、黒背景に縦に積み重ねています。イベント名、日付、時間、会場、服装スタンプを自分の内容に差し替えて、オリジナルのフライヤーを作れます。

Create a vertical 9:16 Halloween party poster with precise, legible English typography. Pure matte-black background, faint black-on-black Gothic stone-arch silhouettes receding into darkness. A huge eclipsed blood moon occupies the upper-middle behind the title: cratered dark burgundy surface, thin arterial-red corona, several glossy blood rivulets running vertically down its lower edge and collecting in a shallow near-black crimson pool. At top, small spaced uppercase text: "ONE NIGHT ONLY" in pale cold-gray narrow serif, centered. Main headline across the central 52% of the poster, two centered lines: "BLOOD MOON" / "BASH". Draw every letter as narrow compressed Gothic blackletter with thick upright stems, hairline diagonals, diamond-point serifs, pointed arches and intact readable counters. The glyphs are saturated with a wet deep-crimson blood film: bright arterial red #CC0000 on convex active streams, dark brown-red recesses, near-black #3D0000 clotting at the lower terminals. At each diamond serif and descender, blood gathers into visible rounded beads with meniscus surface tension; thick sources taper into gravity-pulled threads ending in tear-shaped drops. Fine capillary blood traces follow hairline strokes. Cold directional key from upper-left creates pinpoint white-red specular highlights; a narrow rear rim light outlines every serif and arch in sharp pale-red contours. Blood drips must be heavy and viscous, never watery, while the blackletter remains crisp and readable. Below title, centered small uppercase line: "HALLOWEEN NIGHT · SATURDAY, OCTOBER 31, 2026" in cold-gray serif. Bottom third: a black Gothic banquet table silhouette with three short melted black candles, red wax-blood runnels, a cracked silver chalice and a small pool of clotted crimson liquid, all lit by the moon's low red glow. At bottom, centered: "MIDNIGHT–3 AM" then "THE OLD CHAPEL · 13 RAVEN STREET" in clean pale-gray condensed serif. Add a small circular red-black seal at lower right reading "COSTUMES REQUIRED". Restrained dark-red airborne droplets only, no warm colors, no colorful decorations, high-detail practical-effects photography, sharp print-poster hierarchy.
