Prompt: Please generate a vertical 3:4 high-definition commercial poster, single image, no collage, no multi-grid layout. 

The theme is: [Product Type] New Product Promotion Poster. 
This is an original fictional brand advertisement and does not feature a real brand logo. 
Brand Name: [Brand Name]
Product Name: [Product Name]
Main title in large font: [Main Title]
Subtitle: [Slogan]
Main Tone: [Main Tone]

The overall style is a "giant promotional text perspective poster," with visuals resembling the main visual of an official brand campaign, featuring a sense of commercial advertising, strong layout design, youthfulness, product launch feel, and visual impact. 

[Core Scenes]
The main subject of the image is the [product], which must be clear, refined, and resemble the hero product in advertisements. Add appropriate characters or usage scenarios according to the product type, such as: phone models, runners, riders, skateboarders, athletes, outdoor players, etc. The character's posture should be natural and dynamic, and the product and the person should have a real spatial relationship. 

[Giant Text Perspective]
Main title [main title] must be the core visual framework of the image, using oversized bold sans-serif fonts to occupy the main space of the image. Text cannot be just an ordinary title; it must become the spatial structure of the image, and can become a background wall, ground track, highway, ramp, movement track, or future installation. Characters and products must exist within this vast text space, forming real front-and-back relationships, occlusion relationships, contact shadows, and perspective depth. 

[Official Poster Information System]
The visuals need to have a complete layered brand advertising message to avoid empty space. 
Add the brand name and NEW RELEASE / PRODUCT CAMPAIGN small print at the top. 
Add vertical small font, series number, product number, or campaign number on the side. 
Add 3-5 functional selling point tags near the product, for example: [Selling Point One][Selling Point Two][Selling Point Three][Selling Point Four]. 
Set up an official advertising information bar at the bottom, including product name, slogan, release date, core parameters, small print credits, fine line segmentation, decorative barcode or number. 
Information layout should be refined, restrained, and authentically branded. Small print can serve as design microtypography; not every small print needs to be fully legible, but the brand name, product name, and main title must be clear. 

[Image Quality]
High-definition sharpness, commercial photography texture, authentic materials, accurate perspective, clear product clarity, natural people, and unified light and shadow. Overall, it resembles a real product campaign poster, suitable for mobile phones, digital devices, running shoes, motorcycles, sports brands, events, and other scenarios. 

[Problem Avoidance]
No collages, no multi-image combinations, no real brand logos, no cheap e-commerce images, no ordinary material images, no complex or cluttered backgrounds, no cartoonish looks, don't make the product too small, and don't turn the main title into a plain flat title.
