Концертный арт-постер с крупным планом гигантского инструмента

Generate a 4:5 vertical high-definition concert art poster, with the series theme 【Series Name】 and the individual theme 【Poster Title】. The style is a modern performance poster, high-end concert visual, with the feel of an art-museum poster, magazine-layout sensibility, and a serialized design language. The background uses a 【Background Color】 paper texture, with slight grain, print texture, and soft negative space — no pure-white empty background. The key visual is a giant close-up of a 【Instrument Name】, rendered in realistic 3D / high-end photographic quality, entering from the edge of the frame and boldly cropped. Emphasize 【Material Features】, such as metallic reflections, wood grain, black lacquer, strings, keys, curved structures. The instrument must be realistic, refined, and structurally accurate — no distortion, no cartoon feel. Add 1–2 【Geometric Color Blocks】 to the background, such as circles, semicircles, arcs, thin lines, transparent rings, or moon-phase shapes, to balance the composition. Keep the geometric elements restrained and refined, not too complex. Use an asymmetric layout: large title area + key visual area + small information area. On the left, enlarge the Chinese title 【Chinese Title】, with a clear, complete, well-designed typeface. Add an English subtitle 【English Subtitle】, using an elegant serif font or a modern magazine font. Add a small amount of event information in the corners, for example: DATE / 【Date】 VENUE / 【Venue】 SERIES / 【Series Info】 At the bottom, you may add a small amount of fine-print information, for example: 【Program Type】 【Performance Description】 【Curation Info】 The overall palette is 【Main Color】, keeping it high-end, restrained, and with a concert-hall temperament. The image needs a strong sense of design, a sense of series, material texture, and a clear visual focal point. Avoid: garbled text, typos, wrong instrument structure, too much information, cheap promotional feel, training-class poster feel, ordinary event-flyer feel, excessive decoration, and low resolution.
