Daylight Submarine

Use case: ads-marketing Asset type: commercial movie poster key art, native 3:4 vertical PNG Primary request: create a polished theatrical poster for theme "白昼潜艇". Scene/backdrop: ivory white to pale blue gradient background, clean futuristic environment, a circular submarine hatch shadow falling behind the subject. Subject: Nordic female sonar engineer, 27 years old, focused and competent, viewed from above in near full-body framing. She wears silver-blue sporty haute couture, a short scarf, and holds a transparent sonar waveform board with elegant visible signal graphics. Realistic face and hands, not beauty glamour. Style/medium: premium live-action science thriller poster photography, clean technology aesthetic, subtle film grain, refined modern design. Composition/framing: vertical 3:4 poster, high-angle / overhead perspective toward near full body, circular hatch shadow as graphic anchor, generous clean space for title. Lighting/mood: bright daylight, cool diffused studio-sea light, suspenseful but pristine. Color palette: ivory white, pale blue, silver blue, soft graphite accents. Text (verbatim): title "DAYLIGHT SUBMARINE" large, crisp, professional theatrical typography; tagline "SINK IN PLAIN SIGHT" smaller and clearly readable. Spell text exactly, no extra words. Constraints: native portrait 3:4 composition; clear readable English poster text; professional typography; no watermark; no logos; no text gibberish. Avoid: ordinary headshot, AI beauty face, plastic skin, malformed fingers, wrong earrings, long gloves, anime/game character art, excessive exposed skin, sexual implication, messy background, black-and-gold cliche palette, random extra text, misspelled text.
