Affiche de mouvement vert printanier avec titre citron

Generate a vertical 3:4 spring-day youthful mood visual poster, with the theme «[main title]». Choose one of these scenes as the main subject: spring tram station, convenience store entrance, rainy-night bus stop, airport corridor, tree-lined campus path, riverside cycling, green train, spring bus, rainy street, high-speed subway, cycling youth, seaside highway. The main subject must clearly create the feeling that "spring is passing by": it could be a green tram/bus/subway speeding past, a cycling youth sweeping horizontally across the frame, or a moment at the store entrance, airport corridor, campus path, or riverside road pulled open by wind, light, rain, and motion trails. The background may include a platform, tree shadows, glass reflections, rain-soaked ground, riverside railings, campus benches, store lights, airport glass passage, spring sky, etc., but overall it should not be too clear—treated with horizontal motion blur, scan trails, long-exposure light bands, and slight ghost blur, forming a strong sense of speed, flow, and youthful cinema. The overall style is a spring green experimental visual poster, Japanese-style youth film cover, independent designer magazine layout, trendy graphic design. The palette is dominated by dark green, grass green, tender green, cyan-green, and light fluorescent green, paired with lemon yellow as the text accent color. The image needs glass reflections, soft halo, slight glare, fine paper grain, a sense of moist air, post-rain mist, slow-shutter trails, and a crisp spring breeze; the mood is free, romantic, quiet, and light, like the instant spring rushes past before your eyes. Layout: overlay a huge Chinese handwritten title «[main title]» in the center, in a font like casually written highlighter strokes—thin, elongated, flowing, free, with a sense of speed, in bright lemon yellow. The text should form an overlapping relationship with figures, vehicles, glass reflections, tree shadows, and light bands, as if blown by the wind. At the top and bottom, add lots of extremely fine small English text, year numbers, a barcode, short descriptive text, brand-style layout, and thin decorative lines, creating a refined magazine cover quality. In the upper-right and lower-right corners, add light green arc-cropped color blocks to enhance the modern graphic design feel. Below, add a line of thin white text «[subtext]». The whole should be refined, crisp, youthful, cinematic, magazine-like, and independent-designer-like; no real APP interface, no social platform buttons, no watermark, no garbled characters, no cheap ad feel, no childish illustration feel.
