The overall style is a "Digital Product Giant Font Perspective Campaign Poster." The product must be clearly displayed as a hero product, with accurate proportions, authentic materials, and exquisite details. The character should have the feel of a promotional campaign and a clear pose, and can hold the product, display it, wear it, or use it. 

Main title [Main Title Large Text] Use an oversized bold sans-serif font to occupy the main space of the image. Text should serve as a brand background wall, perspective stage, technology space, ground passage, or product circulation, with a distinct perspective or diagonal perspective, clear and legible, and strong visual impact. Characters, products, and giant text should be within the same spatial logic, with front-and-back relationships, obstruction relationships, contact shadows, and unified light and shadow. 

The screen includes the official brand advertising information system: brand name at the top, campaign small text in the upper right, vertical message on the side, feature highlight icons next to the product, and the bottom infobar containing product name, subtitle, release date, parameters, small text credits, fine lines, and barcodes. Overall, it's high-definition, sharp, high-contrast, and has a tech-driven advertising feel, like a real digital brand campaign poster. 

Avoid: puzzles, real brand logos, cheap e-commerce looks, product distortions, fake faces, messy backgrounds, unclear main titles, weak perspective.
