IMAGE MASTER PROMPT

Create an original award-quality Japanese A4 portrait フェス event flyer, 3:4. Exact headline: 「風と音の、三日間。」 Exact subheading: 「海辺の音楽フェスティバル」. DESIGN PURPOSE: 週末券を販売する. COMPOSITION: 水平線の大きな余白、左下に小さな群衆、日程を巨大な3行で構成. PALETTE: 深い青、砂色、朱赤. Establish a decisive three-level reading order: first the event promise, second date and time, third venue and action. Use at least two strong contrasts among scale, density, light and spacing. Every photograph, crop, color field and typographic shift must have a communicative reason. Professional Japanese design-studio quality, precise editorial grid, crisp photographic detail, accurate legible Japanese, print-safe margins, clear CTA and realistic information hierarchy. Anonymous Japanese adults or families only when required by the concept, with sharp natural faces, hands and anatomy. Create an entirely original design; learn from award-level communication discipline without copying any identifiable designer, artwork, festival identity or Pinterest image. No real event, performer, speaker, venue, sponsor, municipality, logo, trademark, celebrity or watermark. No jagged brush edges, torn paper, grunge, arbitrary corner decoration, generic random rectangles, equal-weight information, blurry faces, malformed people or illegible filler.
