AI Prompt for Anime Romance Poster in Cinematic Style

"A Japanese theatrical romance movie poster in a tall smartphone-style vertical layout with rounded corners, designed like a polished anime key visual. The main image shows a beautiful teenage billboard girl heroine standing on an outdoor balcony at dusk, turning back over her shoulder to look at the viewer with a soft, wistful expression. She has very long silver-white twin-tail hair tied with dark ribbons, pale skin, and large pink-violet eyes. She wears a delicate white frilled blouse with voluminous sleeves and a dark high-waisted dress or corset-like skirt, creating an elegant, slightly gothic school-romance look. The atmosphere is dreamy and emotional, filled with glowing bokeh lights, drifting petals or snow-like sparkles, sunset pink and lavender light, and a luminous cityscape in the blurred background. Use rich cinematic anime rendering, ultra-detailed hair strands, soft rim light, glossy eyes, and a bittersweet first-love mood. Add Japanese poster typography integrated into the composition: a large vertical pink poetic tagline on the right, a vertical white tagline on the left, a very large main title near the lower left reading {argument name="title text" default="看板娘"}, and a smaller subtitle beside it reading {argument name="subtitle text" default="君と紡ぐ恋物語"}. Include 5 small rectangular film-strip preview stills aligned across the lower middle, each showing the same heroine in different emotional close-ups. Add dense credits, festival-style laurels, and small release information at the top and bottom in Japanese, with the overall feel of a premium romance anime film poster advertising a tragic, beautiful love story. Use a pastel palette of mauve, blush pink, violet, pearl white, and midnight navy, with soft bloom, shallow depth of field, and elegant poster composition."
