Generate a 4:5 vertical high-definition concert art poster, with the series theme as [Series Name] and the individual theme as [Poster Title]. The visual style is a modern exhibition poster, sophisticated concert visual, with an art gallery poster feel, magazine layout sensibility, and a serialized design language. The background uses [Background Color] paper texture, with slight grain, print texture, and soft negative space; avoid a pure white empty background. The main visual is a close-up of a giant [Instrument Name], presented with realistic 3D / high-end photographic texture, entering from the edge of the frame and boldly cropped. Focus on highlighting [Material Characteristics], such as metallic reflections, wood grain, black lacquer, strings, keys, and curved structures. The instrument must be realistic, exquisite, and structurally accurate; avoid distortion and cartoonish looks. Add 1–2 [Geometric Color Blocks] to the background, such as circles, semicircles, arcs, thin lines, transparent rings, or moon phase graphics, to balance the composition. Geometric elements should be restrained and sophisticated; avoid excessive complexity. The layout uses an asymmetrical composition: large title area + main visual area + small information area. On the left, enlarge the Chinese title [Chinese Title], with clear, complete, and well-designed typography. 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 of the frame, such as: DATE / [Date] VENUE / [Venue] SERIES / [Series Information] Small text information can be added at the bottom, such as: [Program Type] [Performance Description] [Curatorial Information] The overall color scheme is [Main Color Tone], maintaining a sophisticated, restrained, and concert hall atmosphere. The image must have a strong sense of design, serialization, texture, and a clear visual focus. Avoid: garbled text, typos, incorrect instrument structures, excessive information, cheap promotional feel, training class poster feel, generic event flyer feel, excessive decoration, low resolution.
