Poster fluido dei Mondiali in stile stampa retrò

Generate a vertical 3:4 Chinese World Cup concept poster. The overall style is: fluid art, World Cup visual poster, conceptual sports poster, retro print grain, artistic pitch, dynamic match scene. No ordinary realistic photography, no e-commerce poster feel, no cartoon, no plastic 3D look. The main subject is a "fluidized" football pitch. The grass is not a normal field, but like a flowing canvas formed by interwoven dark green, creamy white and blue, with large areas of curves, rotations, whirlpools, rivers and texture flows, as if water, ink, terrain and speed trails were fused together. The whole ground should look like a flowing match map. Distribute several running footballers across the scene; they are small-scale figures, as if placed on a giant flowing pitch. The poses must have clear motion: sprinting, breaking through, passing, tracking back, dashing, double-teaming, making runs, pressing. The players merge with the flowing terrain, as if running with the current or breaking against the whirlpool. The figures should not be too large; the focus is not a character close-up, but the overall relationship of "players moving within a flowing pitch." There can be one protagonist player, for example a blue-shirt player, a red-shirt player or the number 10, with other players forming attack-and-defense relationships around them. The composition can use a top-down view, an oblique top view, or a poster-style high angle, with clear rhythm and large flowing trails. Goals, a ball, dashed passing lines, movement arrows, swirling flow lines and other elements can be added locally, but with restraint, not turning it into a tactics board. For color, dark green grass is suggested as the main tone, paired with creamy white flowing patterns and local blue water patterns, with a touch of retro grain, old print noise and paper texture. The image must be high-end, artistic, and with match tension. The poster layout must be complete: Main title: "【Main Title】" Subtitle: "The Art of Flow × World Cup Poster" Bottom phrase: "【Bottom Copy】" The Chinese must be clear, accurate, and free of garbled characters. No watermark, no real brand logos, no messy English, and not made into an ordinary promotional page.
