Design a high-fidelity, aesthetically refined, and professionally composed commercial poster for the 'Double 11 Shopping Carnival'. This is not a generic template, a simple collage, a low-quality e-commerce image, or a default AI-generated picture. It must resemble a premium poster crafted by a professional visual designer for a brand's key visual, event promotion, product launch, social media cover, or commercial advertisement. The poster should not only have visual impact but also demonstrate true design logic, aesthetic judgment, layout order, typographic design for the title, color control, and commercial completeness. Avoid mere 'element richness'; pursue sophistication, unity, restraint, hierarchy, and design sensibility. First, understand the theme and translate it visually. Then, design the layout before the imagery. The poster must have a clear focal point, distinct hierarchy, logical reading flow, stable alignment, rhythmic whitespace, unified visual language, and orderly element distribution—not crowded, not uniform, not chaotic. Choose an advanced composition like center focus, large whitespace, left-right columns, top-bottom sections, diagonal dynamics, geometric order, text-led, image-text fusion, product studio, magazine cover, art exhibition, or brand key visual. The main visual should be memorable, such as a product, character, 3D object, abstract shape, metaphor, brand symbol, giant title, photographic still life, conceptual scene, illustration, artistic icon, or spatial installation, serving the theme with first-glance appeal. For the title, redesign the font structure with techniques like stretching, compressing, angling, rounding, slanting, breaking, connecting, overlapping, sharing strokes, negative space reconstruction, geometric simplification, or curving, ensuring unity in weight, center, stroke thickness, corner logic, ending style, curve language, black-white balance, and inter-character rhythm. Keep it readable in Chinese. Decide layout first (horizontal, vertical, line breaks, offset, stacked, layered, block, or integrated with graphics). Short titles can be focal; long titles need rhythm. The title must have a visual memory point, like a strengthened stroke, unique structure, connection between characters, unified block shape, distinctive negative space, or fusion with the main visual. Arrange text with clear hierarchy: main title largest and most designed, subtitle explanatory, core info concise, and date/location/slogan/logo as supporting elements. Ensure clear alignment, hierarchy, rhythmic spacing, reasonable whitespace, grid order, visual breathing, and harmony with the main visual. Use a restrained, sophisticated, and unified color scheme. Add subtle details like fine lines, grain, paper texture, small English text, branded symbols, geometric borders, info tags, soft shadows, semi-transparent materials, studio lighting, slight noise, grid lines, directional arrows, or data icons, but only to enhance completeness without overwhelming. The aesthetic should reflect professional judgment: a focal point, hierarchy, whitespace, unified font logic, advanced color control, strong memory point, commercial appeal, layout order, and design completeness. Prefer restraint, cleanliness, and order over flashiness, crowding, or showing off. Reference professional brand posters, art exhibition posters, commercial ad key visuals, magazine covers, brand launch KVs, Behance advanced visual designs, Dribbble brand visuals, or Pinterest high-aesthetic graphic designs. Output as a 9:16 high-definition image with high fidelity, refined details, and complete composition.
