Generate a vertical 3:4 spring-youth mood visual poster on the theme “[main title]”. Choose one scene as the main subject: a spring tram stop, a convenience-store entrance, a bus stop on a rainy night, an airport corridor, a tree-lined campus path, riverside cycling, a green train, a spring bus, a rainy street, a high-speed subway, a cycling boy, a seaside road. The subject must clearly convey the feeling that “spring is passing by”: a green tram / bus / subway speeding past, a cycling boy sweeping horizontally across the frame, or a moment at the store entrance, airport corridor, campus path, or riverside road torn open by wind, light, rain, and motion trails. The background may show a platform, tree shadows, glass reflections, rain-soaked ground, riverside railings, a campus bench, store lights, an airport glass passage, a spring sky — but kept not too clear, treated with horizontal motion blur, scan trails, long-exposure light streaks, and slight ghost blur, creating a strong sense of speed, flow, and youthful cinematic feel. The overall style is a spring green visual-experiment poster, a Japanese youth-film cover, an indie-designer magazine layout, trendy graphic design. The palette is dominated by deep green, grass green, tender green, teal, and pale fluorescent green, with lemon yellow as the text accent color. The image needs glass reflections, soft halo, slight glare, fine paper grain, humid air, post-rain mist, slow-shutter trails, and a clear spring-breeze feel; the mood is free, romantic, quiet, and light, like an instant of spring rushing past your eyes. Layout: overlay a giant handwritten Chinese title “[main title]” at the center, the font like a casually scrawled highlighter — thin, elongated, flowing, free, with a sense of speed, in bright lemon yellow. The text should overlap with people, vehicles, glass reflections, tree shadows, and light streaks, as if blown by the wind. At the top and bottom, add lots of very fine English small text, year numbers, a barcode, short blurbs, brand-like typesetting, and thin decorative lines, creating a high-end magazine-cover air. In the top-right and bottom-right corners, add light-green arc-cut color blocks to strengthen the modern graphic-design feel. Below, add a line of thin white copy “[subtext]”. The whole must be high-end, crisp, youthful, cinematic, magazine-like, and indie-designer-like; no real app interface, no social-media buttons, no watermark, no garbled text, no cheap-ad feel, no childish illustration look.
