Dynamic Japanese-style sports poster featuring a black-clad footballer kicking a ball against a red sun and the letter 'J

Prompt

Create a dynamic vertical sports poster in a sharp Japanese football graphic-design style. Canvas: portrait 2:3 ratio, off-white paper background with slight grain. Main subject: exactly 1 black-and-white illustrated soccer player in Japan national team kit, jersey number 10, captured mid-kick with one leg extended toward the viewer, dramatic ink splatter shading, messy black hair, and a soft square gray blur obscuring the face. Add exactly 1 black-and-white soccer ball in the lower-left foreground, flying outward with perspective. Behind the player, place exactly 1 huge bold black letter J with a white outline and red offset shadow, partially covering exactly 1 large red sun circle centered behind the athlete. Surround the figure with explosive abstract geometry: diagonal blue speed bars, red and black streaks, yellow accent lines, thin technical drafting lines, halftone dot clusters, small square pixels, splatter marks, and angular shards radiating from lower left to upper right. Use a limited palette of black, white, deep royal blue, vivid red, and small yellow accents. Composition should feel like a modern Japan soccer campaign poster, high contrast, energetic, urban, and print-ready. Bottom right contains small date text May 15, 2026 above a handwritten signature Oyagi. No extra logos, no extra players, no additional readable text.
