[Purpose]
Cinematic movie-poster-style YouTube thumbnail built from the attached portrait, designed to stop scrolling instantly.
High-contrast hero composition with bold Korean title copy, believable theatrical-poster details, and YouTube thumbnail hooks optimized for widescreen readability.

[Composition]
- Main subject placement: {원본 보존} placed as the dominant hero cut on the left 55–60% of the frame, shoulders and face enlarged for immediate recognition, with hairline rim light and cinematic skin texture.
- Title placement: {메인 제목} on the right 30–35% in a stacked poster layout, with the most important words in the upper-right quadrant and thick shadowed separation from the background.
- Supporting copy: {부제목} and {장르 톤} placed under the main title like a theatrical teaser tagline, with compact spacing and readable Korean typography.
- Background treatment: {시각 컨셉} expanded with wet asphalt reflections, bokeh streetlights, distant silhouettes, smoke haze, flying dust or rain particles, and layered cinematic depth that supports the face and title.
- Poster / thumbnail information: include {개봉일}, {감독명}, {출연진}, {관람등급}, {러닝타임}, {채널 핸들}, and {조회유도 문구} as believable micro-copy around the title and lower band.
- Visual framing: poster-like crop, slightly off-center, with dramatic edge falloff, subtle vignette, diagonal light streaks, and a bold accent shape behind the title for instant YouTube impact.

[3. CORE STRUCTURE]
1. Hero portrait area (left side, mid 60%): {원본 보존} cleanly integrated as the central cinematic subject, with intense expression, sharp facial clarity, visible fabric detail, natural skin texture, and pronounced depth separation from the background.
2. Background layer: apply {시각 컨셉} with moody environmental detail, including neon signage blur, reflected pavement, distant vehicle lights, atmospheric smoke, rain specks, ember-like particles, or natural silhouettes depending on the chosen genre.
3. Title block: render {메인 제목} large and high-contrast on the right, with poster-style stacking, tight line breaks, bold Korean display lettering, and a warm amber or white highlight on the key word.
4. Tagline and genre area: place {부제목} and {장르 톤} near the title, using smaller but crisp type to reinforce a real Korean film poster / trailer thumbnail feel.
5. Theatrical detail band: add {개봉일} as a release-date stamp near the lower-right, {감독명} and {출연진} as small credits along the bottom, plus {관람등급} and {러닝타임} as compact info chips.
6. YouTube hook layer: add {채널 핸들} in the top-left or lower-left corner, a small accent emoji or warning badge using {강조 아이콘}, and {조회유도 문구} as a short punchy label near the title.
7. Color grading layer: apply {컬러 톤} across the full frame with deep blacks, controlled highlights, selective glow around the subject edges, and reflective amber/teal light that ties the portrait to the environment.
8. Thumbnail finishing: add crisp cinematic outline separation, subtle film grain, fine dust texture, gentle lens bloom, and a dramatic contrast boost so the face, main title, and key hook remain readable on mobile screens.

[4. STYLE RULES]
- Typography: bold cinematic Korean display style, using Pretendard ExtraBold or Noto Sans KR Black for the main title, with compact poster-like tracking and 68–92px title size equivalent.
- Supporting type: use Noto Sans KR Medium or Bold for genre text, tagline, release-date stamp, and YouTube hook, around 24–36px equivalent, clean and highly legible.
- Micro credits: use condensed Korean/Latin credit styling along the lower edge, 14–20px equivalent, with believable spacing like a movie poster billing block.
- Color palette: {컬러 톤} anchored by deep charcoal #111111, warm amber highlights #D98B2B, teal accents #2F6F75, emergency red #C92A2A, and off-black shadows #080808.
- Graphic accents: use one bold diagonal shape, torn-poster texture, light flare streak, countdown badge, or red warning tag to add thumbnail urgency while maintaining a premium cinematic poster look.
- Border/shadow: subtle poster-edge vignette, soft drop shadow 4px y-offset, 14px blur, 18% opacity behind text blocks, with no cartoon outline.

[5. VISUAL STYLE]
- Camera / lens: 85mm cinema portrait look, f/1.8 depth separation, shallow depth of field, strong subject isolation, poster-grade sharpness on the face.
- Lighting: hard backlight/rim light from upper-right, controlled fill from lower-left, with nighttime practicals or reflective ambient sources to create bold specular edges.
- Color grade: teal-orange cinematic grade with charcoal blacks, amber skin highlights, cool blue-black background compression, and realistic film-poster grain.

[6. MOOD]
High-stakes cinematic trailer-poster energy — a modern Korean blockbuster teaser thumbnail with the intensity and contrast of a Denis Villeneuve / Bong Joon-ho promotional frame, upgraded with realistic Korean release information and clickable YouTube drama.

[7. CRITICAL]
- Korean text accuracy: {메인 제목}
- Korean text accuracy: {부제목}
- Korean text accuracy: {장르 톤}
- Korean text accuracy: {개봉일}
- Korean text accuracy: {감독명}
- Korean text accuracy: {출연진}
- Korean text accuracy: {관람등급}
- Korean text accuracy: {러닝타임}
- Korean text accuracy: {채널 핸들}
- Korean text accuracy: {조회유도 문구}
- Korean text accuracy: {강조 아이콘}
- Preserve the attached person's identity exactly; change only the expression to a stronger cinematic emotion.
- Face must remain clearly recognizable, and the main title must be fully readable at thumbnail size.

[8. 🚫 PROHIBITED]
- Fake official seals / certifications
- Broken Korean characters or unreadable Korean typography
- Celebrity face composites unless the celebrity is supplied in reference_image
