Please generate a vertical 3:4 high-definition commercial advertising poster, single image, no collages, no multi-grid layouts. Theme: [Product Type] new product promotion poster. This is an original fictional brand advertisement; do not include any real brand logos. Brand Name: [Brand Name] Product Name: [Product Name] Main Headline (large text): [Main Headline] Sub-headline: [Slogan] Main Color Palette: [Main Color Palette] Overall style: "Product promotion giant typography perspective poster." The image should look like an official brand campaign key visual, featuring a commercial advertising feel, strong layout design, youthful energy, product launch atmosphere, and visual impact. 【Core Visual】 The main subject is [Product]; the product must be clear, exquisite, and look like a hero product in an advertisement. Include appropriate characters or usage scenarios based on the product type, such as: phone model, runner, rider, skateboarder, athlete, outdoor enthusiast, etc. Character poses should be natural and dynamic, with a realistic spatial relationship between the product and the character. 【Giant Typography Perspective】 The main headline [Main Headline] must be the core visual skeleton of the image, using extra-large bold sans-serif fonts that occupy the main space of the frame. The text should not just be a standard title; it must become the spatial structure of the image, transforming into background walls, floor runways, highways, ramps, motion trajectories, or futuristic installations. The character and product must be situated within this giant typographic space, forming realistic foreground-background relationships, occlusion, contact shadows, and perspective depth. 【Official Poster Information System】 The image needs a complete brand advertising information hierarchy to avoid empty space. Top: Add the brand name and small text "NEW RELEASE / PRODUCT CAMPAIGN". Side: Add vertical small text, series numbers, product codes, or campaign numbers. Near the product: Add 3-5 feature highlight tags, such as: [Feature 1][Feature 2][Feature 3][Feature 4]. Bottom: Set up an official advertising information bar, including the product name, slogan, release date, core specifications, small credit text, thin line dividers, and decorative barcodes or serial numbers. The information layout should be exquisite, restrained, and possess a sense of authentic brand guidelines. Small text can serve as design-oriented micro-typography; while not every small character needs to be perfectly legible, the brand name, product name, and main headline must be clear. 【Image Texture】 High-definition and sharp, commercial photography texture, realistic materials, accurate perspective, clear product, natural characters, and unified lighting. The overall result should look like a real product campaign poster, suitable for scenarios such as mobile phones, digital devices, running shoes, motorcycles, sports brands, or event promotions. 【Avoidance Criteria】 No collages, no multi-image combinations, no real brand logos, no cheap e-commerce graphics, no generic stock photos, no complex or cluttered backgrounds, no cartoonish feel, do not make the product too small, and do not let the main headline become a standard flat title.
