프롬프트

[Input]
- language: Korean
- output_size: 1536x1024

[Purpose]
Korean YouTube thumbnail for mukbang, vlog, and daily-life content. 16:9 horizontal click-through design with realistic creator-studio energy, high-impact food detail, expressive face emphasis, and believable YouTube overlay elements.

[Composition]
- Main subject placement: {피사체} dominates the left-center 60-70% of the frame, with the face and fried chicken held close to the camera for instant visual impact; include visible fingers, sauce shine, crispy texture, and a few natural crumbs for realism.
- Text placement: {메인 텍스트} sits large across the right half or upper-right, designed as a bold Korean clickbait headline with strong stroke, shadow, and a yellow marker-style highlight behind key words.
- Subtitle placement: {서브 텍스트} stays smaller near the lower-right or upper-right, paired with a compact episode label such as "EP.42 야식대전" or "오늘의 먹방" so the thumbnail feels like part of a real channel series.
- Accent shape placement: include a bright yellow arrow, red burst, or emoji-style reaction mark near the food or open mouth; add a small circular callout reading "진짜?!" or "한입만" to guide attention.
- Background treatment: realistic indoor vlog background with warm kitchen or dining-room details softly blurred: table edge, delivery box, sauce cups, drink cup, small LED light reflection, and cozy wall tones that support the mukbang theme without overpowering the subject.

[3. CORE STRUCTURE]
1. Hero subject area: {피사체} in a tight close-up, face centered slightly left, mouth open wide in surprise, eyes bright, hands visible, holding glossy crispy fried chicken close to the lens; add realistic highlights, oil sheen, crumb texture, and slight perspective exaggeration.
2. Main headline area: {메인 텍스트} placed bold and oversized on the right side, with vivid red fill, thick black outline, white inner shine, and a yellow highlight stroke cutting under part of the phrase for Korean YouTube clickbait emphasis.
3. Subtitle and series info area: {서브 텍스트} placed as a small but readable white or yellow text block with black stroke; include small Korean metadata-style text such as "EP.42 야식대전", "오늘 밤 11시", or "치킨 3종 비교" in a compact label strip.
4. Channel and engagement details: add a tiny channel handle like "@daily_mukbang" near the bottom edge, a small play icon, a red "NEW" tag, and a compact view-bait label such as "실시간 반응" or "끝까지 보면 반전"; keep these secondary to the main text.
5. Accent graphics: one yellow arrow pointing to the chicken, a red burst behind a short Korean callout, and one small emoji-like shape such as "😱" or "🔥" integrated into the design for energetic thumbnail impact.
6. Realistic vlog context: background includes warm indoor lighting, blurred delivery food packaging, napkins, sauce containers, and a drink cup on the table, with depth-of-field separation so the creator, chicken, and headline stay dominant.

[4. STYLE RULES]
- Typography: bold Korean sans-serif such as Pretendard ExtraBold or Noto Sans KR Black for {메인 텍스트}; subtitle and micro-labels use Pretendard Medium or Noto Sans KR Regular with strong outline for thumbnail readability.
- Color palette: vivid red, black, bright yellow, white, warm skin tones, golden fried-chicken browns, and cozy indoor beige/orange background tones; make the reds and yellows punchy like a Korean variety-show thumbnail.
- Border/shadow: main text uses thick black stroke with a heavy soft drop shadow; subject cutout can have a subtle 4px y-offset shadow, 12px blur, 20% opacity for separation; add a thin white rim light around the subject if needed for better pop.
- Graphic treatment: use layered sticker-style shapes, marker highlight strokes, comic burst accents, and small UI-like labels to make the thumbnail feel edited by a real YouTube creator.

[5. VISUAL STYLE]
- Camera / lens: 35mm or 50mm smartphone-to-editorial close-up look, f/2.0 to f/2.8 depth-of-field feel, framed like a sharp YouTube thumbnail portrait.
- Lighting: bright frontal key with slight upper-left fill, mild shadow control on the face, glossy highlights on the fried chicken, and warm practical background light for a real mukbang studio atmosphere.
- Color grade: high-saturation pop color grade with warm skin tones, punchy reds and yellows, crisp contrast, slightly lifted midtones, and realistic food texture clarity.

[6. MOOD]
High-energy Korean mukbang thumbnail — fast-paced YouTube clickbait energy with a friendly, mass-market variety-show feel, realistic food excitement, and a lively creator vlog atmosphere.

[7. CRITICAL]
- Korean text accuracy: 반드시 정확히 보여야 하는 문자열: "이걸 다 먹는다고?!", "EP.42 야식대전"
- Face expression must be clearly surprised, mouth open wide, and the food must be visibly recognizable as fried chicken with crispy golden texture.
- The composition must remain thumbnail-readable at small size, with the subject and headline not overlapping in a way that harms legibility.
- Include believable small Korean thumbnail details such as "@daily_mukbang", "NEW", "진짜?!", or "끝까지 보면 반전" only as secondary accents.

[8. 🚫 PROHIBITED]
- Fake official seals / certifications
- Broken Korean characters
- Overly threatening or grotesque food expression
