Generate a bright, clear, and ceremonial visual poster around any subject: The composition establishes a primary order through a strict central axis, with the main form or symbolic structure of the subject standing at the distant vanishing point, elevated like a monumental landmark while maintaining clear details; the foreground spreads out a wide subject field that converges toward the center, with sidelines, stepped tiers, or structures on both sides forming a strong perspective corridor, and a small-scale viewer avatar or subject carrier placed below the center as a scale anchor. The upper portion leaves an open, high-brightness light field with a strong sense of ventilation, allowing light circular symbols derived from the subject to float along both sides of the central axis from large to small, scattered front to back, creating a rhythm and depth like a ball rain, which must not dissipate into ordinary decoration. If text appears, place it before the main visual at the top, using a spacious uppercase feel, clean geometric strokes, large letter spacing, and two font sizes; the information color should be clear and restrained, sharing the central axis with the main form; the bottom features a small circular seal and a short sentence as a conclusion, without overshadowing the main visual. Colors are extracted from the subject's own materials, scene mood, and cultural semantics, retaining large areas of high-brightness clear base colors, wide warm or warm-cold balanced ground color blocks, a small amount of high-saturation glowing accent colors, clear dark information text, and clean shadow role relationships; the overall feel is bright and light, with sufficient airiness, clear color gradients, and textures consisting only of fine print grain and soft sunlight, avoiding gray, dull, turbid, or crowded collage feelings.
