"BEST COSTUME WINS $100" は、仮装コンテスト向けの縦型ストーリーポスターで、ダークで上品なスタイルです。彫刻のような金属光沢を持つ金色のセリフ体の大文字が、黒い羽根付きの黒と金の仮面の下に積み重なり、黒地に細い装飾の枠が添えられています。賞金、曜日と時間を自分の内容に変えたり、見出しを別のイベント文に差し替えたりして作り直せます。

Create a finished 9:16 vertical Halloween costume-contest story graphic, designed for instant phone-screen reading. Commit to an elegant-gothic masquerade register: a deep matte-black velvet background with restrained antique-gold ornament, no gore, no extra lettering, no app interface, no logos, no QR codes. Keep the top and bottom edges open and uncluttered; place all key content within generous safe margins. In the middle band, show one ornate Venetian masquerade mask as the hero prop, centered above the headline. Build it from black enamel, chased antique-gold filigree, and a few fine black feathers; crisp carved edges, subtle gold-leaf highlights, realistic metal reflections. Add a sparse pair of thin engraved gold flourishes framing the central content, not competing with the text. Set the exact headline “BEST COSTUME WINS $100” in very large, perfectly legible custom high-contrast serif capitals, broad enough to read at thumbnail size. Use compact proportions, sturdy main strokes, sharp wedge serifs, open counters, and generous tracking. Render as raised antique-gold foil with fine brushed grain and a narrow dark bevel; no drips, cracks, glow, or letter distortion. Break only if needed for readability, keeping the phrase intact and dominant. Below it, set the exact detail line “Friday at 10 PM” in a smaller but clearly readable refined serif, centered, in flat warm gold. Maintain strong contrast against black and crisp letter edges. Composition: mask occupies the upper part of the central band; headline and detail line form a centered two-tier stack directly beneath it. Preserve generous black negative space above and below the middle-band composition. High-contrast studio lighting, controlled gold rim light on the mask, subtle velvet texture, clean premium print finish, sharp typography, no additional words.
