动漫角色街头风海报设计

Create a stylized anime poster of {character_name} from {franchise}. Analyze the character's canon personality and signature color, then build the design around them. Style: anime × streetwear × graphic poster, clean lineart, semi-flat shading, high contrast, modern minimal look. Pose & expression should match the character archetype (heroic, calm, mysterious, aggressive). Reimagine the outfit as modern streetwear/techwear while keeping iconic identity elements. Composition: vertical ({aspect_ratio}), off-center placement, strong diagonal flow, layered depth. Colors: mostly white background, signature color as main accent plus one complementary accent. Use abstract geometric shapes, negative space, energy strokes, paint lines, and motion effects. Lighting: sharp directional light, crisp shadows, subtle colored glow. Ultra-clean vector-style rendering, poster-quality, 4K detail.
