AI Prompt for Anime Fantasy Key Art Design: Generate a Cinematic Poster

"Create a dramatic vertical anime movie poster in a polished modern Japanese fantasy style, with a deep navy, violet, and sunset-orange color palette, cinematic rim lighting, falling red petals, icy crystal shards, and glowing magical particles. The poster features exactly 6 characters arranged in a dense ensemble composition: 1 central black-haired teenage boy in a dark cloak holding a radiant blue crystalline star-shaped weapon at the lower center, his face obscured by a soft square blur; 1 white-haired young man in a white military-style coat on the left, turned in profile, face obscured by a soft square blur; 1 pink-haired young girl in a white academy uniform at the lower left clasping her hands, face obscured by a soft square blur; 1 long dark-blue-haired young woman on the right wearing a black sleeveless outfit and carrying a sword, face visible and looking determined; 1 blond young man in a pale coat at the lower right, face obscured by a soft square blur; and 1 ethereal pale-haired female figure looming behind them at the top, partially hidden, with her face covered by a large muted rectangular block. In the background, show a towering gothic castle or cathedral spire rising into a glowing dusk sky on the right, with dark flowing hair-like shapes and starry night textures sweeping across the upper left. Add exactly 8 text elements: large vertical Japanese slogan on the left reading {argument name="left slogan" default="世界の真実を、取り戻せ。"}, a smaller vertical phrase beside it reading {argument name="small left phrase" default="この運命に、抗え"}, vertical Japanese copy on the right reading {argument name="right slogan" default="絶望が支配する世界で、少年は――"}, small production copy above the title reading {argument name="production line" default="完全新作オリジナルTVアニメーション"}, a large luminous Japanese title at the bottom center reading {argument name="main title" default="星灰のレゾナンス"}, a spaced Roman subtitle below it reading "SEIKAI NO RESONANCE", a release line reading "2025年 TVアニメ放送開始", and tiny staff/cast credits plus a final tagline along the bottom reading "信じる意志が、未来を変える". Use elegant Japanese poster typography, high contrast, layered depth, painterly detail, sharp highlights on fabric and hair, and a premium theatrical key visual composition."
