[Purpose]
Korean beer advertisement poster, vertical A4-style campaign key visual, premium photoreal commercial look.
Designed for a crisp, high-energy alcohol brand promo with a cold, refreshing night-event atmosphere, including realistic poster information such as event date, venue, ticket notice, sponsor strip, and responsible drinking details.

[Composition]
- Main bottle hero occupies the center 45% of the frame, slightly forward in perspective, with {hero 비주얼} as the visual anchor.
- Headline sits in the upper 18% area, large and bold, with {메인 헤드라인} clearly separated from the hero object.
- Subcopy is placed directly below the headline in a compact block, aligned left or center depending on balance, using {부카피}.
- Add a small event header near the top edge with {이벤트명}, {행사 일정}, and {행사 장소}, designed like a real seasonal campaign poster rather than a plain product ad.
- Background crowd stays concentrated in the lower-left and lower-center zones, using {배경 군중} to create concert-festival energy while the bottle remains dominant.
- Tag/info elements appear in the lower corners and footer strip, especially {태그·정보}, {티켓 정보}, {SNS·문의}, and {브랜드 정보}.
- Include a sponsor/support area in the bottom footer using {스폰서 영역}, styled as small typographic sponsor marks and simple logo-like text blocks.
- Add icy decorative graphics from {장식 그래픽}: fractured ice shards, cold mist, metallic silver streaks, small snowflake icons, splash trails, and light flares integrated around the bottle and headline.
- Keep the layout tall, poster-like, and layered: event header → headline/subcopy → hero splash → lifestyle/crowd energy → ticket/sponsor/footer details.
- Use {브랜드·제품명}, {브랜드 정보}, and {인물·lifestyle 컷} as coordinated campaign content, but keep the hero poster as the primary focal point.

[3. CORE STRUCTURE]
1. Top campaign band: place {이벤트명} as a small but premium event label, then place {메인 헤드라인} in a strong advertising masthead style, spanning most of the width, with the smaller {부카피} tucked beneath in a clean supporting line.
2. Main hero zone (mid 50%): render {hero 비주얼} as a photoreal bottle centerpiece with icy splash arcs, flying condensation droplets, cracked ice pieces, and cold vapor, lit to emphasize glass highlights and metallic label detail.
3. Event detail ribbon: integrate {행사 일정}, {행사 장소}, and {티켓 정보} as believable poster information on a metallic-silver or translucent ice-blue ribbon crossing the lower-middle or lower-right area.
4. Lower energy zone: build {배경 군중} as a deep-blue nightlife silhouette layer, with raised arms, bottles catching light, stage beam lights, confetti-like ice particles, and subtle motion blur only in the background.
5. Lifestyle insert: incorporate {인물·lifestyle 컷} as a natural auxiliary visual thread, like a small diagonal photo-strip, reflective glass panel, or background vignette connected to the same brand event mood.
6. Info/footer layer: place {태그·정보}, {SNS·문의}, {브랜드 정보}, {푸터 고지}, and {스폰서 영역} in the lower area as crisp campaign details, legible against the darker blue background.
7. Brand lockup: show {브랜드·제품명} as a clear product identity near the bottle label or lower-right lockup, matching the cold metallic beer campaign style.

[4. STYLE RULES]
- Typography: use Pretendard ExtraBold or Noto Sans KR Black for the headline, with 72–96px scale feel; use Pretendard Medium or Noto Sans KR Regular for subcopy and event details at 24–36px feel.
- Color palette: {컬러 톤}; use cold contrast between deep blue background, crisp white typography, ice-blue splash, metallic silver shadows, and selective gold accent highlights.
- Layout: follow {레이아웃}; make the poster feel like a finished outdoor campaign piece with real-world text hierarchy, event information, sponsor footer, and drink-responsibility notice.
- Border/shadow: use polished poster edges, soft shadow under bottle 4px y-offset, 14px blur, 18% opacity; add realistic glow on splash highlights, ice shards, condensation, and stage beams.
- Typography treatment: headline can include metallic beveling, frosty edge texture, cold vapor around strokes, and selective silver highlights while remaining sharply readable.
- Decorative system: use {장식 그래픽} as energetic supporting elements that wrap around the bottle and headline, with realistic reflections on glass and ice.
- Sponsor/footer styling: {스폰서 영역} should look like small printed partner marks, ticket partners, venue support labels, and event-operating notes, not as fake official certification seals.

[5. VISUAL STYLE]
- Camera / lens: Hasselblad X2D 100c with XCD 80mm f/2.8, ISO 100, f/4 commercial product-shot clarity; optional Sony A7R V with 50mm f/1.4 for lifestyle cut integration.
- Lighting: hard-soft studio key from upper-left at 45°, cool rim light from upper-right, controlled specular highlights on bottle glass, faint fill from front-center to preserve label readability.
- Color grade: cold night-blue base with silver-white highlights, restrained gold accents, and crisp contrast reminiscent of premium beer campaign photography.
- Texture realism: realistic glass thickness, wet label edges, condensation beads, melting ice, water splash refraction, printed poster ink sharpness, and believable night-event haze.

[6. MOOD]
Premium Korean beer campaign key visual with a nightclub-festival editorial energy, like a high-end Cass seasonal poster shot in a modern commercial studio and finished as a real event promotion poster for a summer night beer festival.

- Bottle, splash, crowd silhouettes, event ribbon, sponsor footer, and lifestyle people must feel like a single coordinated campaign shoot.
- If people appear, hands and faces must be anatomically correct, with natural crowd proportions and no distorted fingers.
