Manga Heroine Farewell Poster AI Image Prompt

Goal: Create a bold vertical farewell poster with monumental typography and a manga heroine, themed around {argument name="headline text" default="GOOD BYE!"}. Canvas: Portrait poster, 2:3 aspect ratio, deep saturated cobalt-blue background, high-contrast screen-printed / risograph look. Layout: Fill almost the entire canvas with enormous condensed bold sans-serif capital letters. Use exactly 8 visible headline characters arranged in two rows: top row has 4 letters spelling "GOOD"; bottom row has 4 characters spelling "BYE!". The letters are white with blue halftone cloud imagery inside them, as if the sky is clipped into the text. Leave narrow blue gaps between characters. Place the figure in the lower center, overlapping the bottom row and partially covering the middle of "BYE!". Add small date text "May 26, 2026" and a small cursive signature in the lower-right corner. Subject details: A black-and-white manga-style Japanese schoolgirl in a sailor uniform stands from mid-thigh up, looking upward with her head tilted back. She has {argument name="hair color" default="black"} long windblown hair streaming to the right, detailed ink linework, halftone shading, a sailor collar, short sleeves with dark stripes, a tied neckerchief, and a dark pleated skirt. Her face is intentionally obscured by a soft vertical gray blur rectangle, creating an anonymous, poster-like effect. Visual style: Dramatic Japanese manga illustration combined with graphic editorial typography, monochrome character art against electric blue, dense halftone dot texture, weathered print grain, high contrast, sharp ink outlines, summer sky and cloud motif inside the letters, energetic wind motion. Text content: Use the exact large headline "GOOD BYE!" with the exclamation mark as the final character. Include the small lower-right date {argument name="date text" default="May 26, 2026"} and a small cursive signature {argument name="signature" default="Oyagi"}. Constraints: Keep the composition poster-like and typography-dominant; do not add extra characters, logos, borders, or additional text. Ensure the headline remains legible despite the cloud texture and the figure overlap.
