AI Prompt for Fantasy Movie Poster with Plush Penguin Mascot

"A heartwarming fictional movie poster in a soft cinematic Japanese drama style, photographed at golden hour with dreamy backlight and gentle lens glow. A person seen from behind and slightly below, wearing a cozy cream knit sweater, lifts a plush penguin toy high toward a bright sunset sky. The plush is centered and fills much of the frame: black fuzzy body, white belly, small yellow beak, yellow feet, outstretched stubby wings, and a humanlike anime-girl face framed by short dark brown bobbed hair with hairpins, creating a cute surreal mascot character. The background is an outdoor field with warm bokeh trees and a glowing sun low on the horizon, all in creamy beige, honey, peach, and gold tones. Several white feathers float through the air; show exactly 5 visible feathers scattered around the composition. Make the mood tender, nostalgic, hopeful, and slightly fantastical, like a family fantasy film poster. Add Japanese poster typography integrated into the design: at the top center, the tagline "この出会いが、世界をやさしく変えていく。"; along the left side vertically, "ずっと、いっしょだよ。"; near the bottom center, a large handwritten glowing title "{argument name="movie title" default="GUGUGAGA"}" in warm white neon-like script with a small pink heart above it; directly below in elegant serif capitals, "{argument name="subtitle" default="THE MOVIE"}". Beneath that, place a pink ribbon banner with the Japanese line "ずっと、いっしょだよ。". At the very bottom, add small centered Japanese credit text in a realistic film-poster layout, including cast and staff lines and production/distribution credits; include "gugugagaTokyo" and "AI Studio Tokyo" on the final line. Use a vertical one-sheet poster composition, polished commercial key art, shallow depth of field, soft filmic contrast, premium cinematic lighting, sentimental fantasy-drama aesthetic."
