Male minimalist product urban street premium

Objective: Create a clean square fashion product advertisement for Urban Sling Bag, using a minimalist Japanese e-commerce/catalog aesthetic. Canvas: 1:1 square image, bright white to very light gray studio background, high-key lighting, clean commercial photography, no border or watermark. Layout: split composition, left third for large typography, right two-thirds for a male model. The model is framed from above the thighs to above the head, standing relaxed with both hands in his pockets. Leave ample negative space around the text on the left. Subject details: a young East Asian male model with short black curly hair, his face obscured by a smooth rectangular skin-tone blur block. He wears an oversized solid crewneck T-shirt and loose dark trousers. An triangular Urban Sling Bag is slung diagonally across his torso, from his right shoulder to his left waist. The Sling Bag has a wide black strap and buckle, a clean matte fabric texture, a diagonal zipper with black pull cord on the front, a small zipper pull on the side, and a tiny rectangular brand label near the lower right edge. The bag should be the visual focus. Text content: include 4 groups of text on the left: 1) a large stacked uppercase headline , using a bold modern sans-serif font with wide letter spacing; 2) two lines of smaller Japanese feature copy ; 3) a short thin horizontal divider line; 4) a small product code . Keep the text color dark charcoal gray, left-aligned, with a layout like a premium catalog poster. Visual style: realistic studio product photography, crisp fabric details, soft shadows, monochrome black-and-white style, modern Japanese streetwear catalog design, premium minimalism. Constraints: use only one model, one Sling Bag, one T-shirt, one pair of trousers, and four groups of text. Do not add extra accessories, logos, background, props, decorative graphics, or extra text.
