Premium Fashion-Tech Screen-Print Poster

Create an ultra-premium vertical advertising poster for a fictional fashion brand, styled as a collectible, world-class fashion-tech campaign: graphic, youthful, intellectual, luxurious, and product-focused.

Feature ${product-description} prominently. Center a young adult man in a waist-to-mid-thigh crop, viewed slightly from below. Give him an almost upright pose with a gentle curve, a slightly raised and tilted head, and a visually elongated neck. His expression and presence should feel calm, confident, and stylish. Do not resemble any celebrity or real person.

Create a dense, flat cobalt-blue field with a fine technical grid, registration marks, sparse scuffs, silkscreen traces, and print-layout markings. Use a dense, rich mustard-yellow field as the dominant final screen-print layer, retaining the cobalt technical details. Avoid realistic environments, interiors, streets, and unnecessary props.

Render the image as world-class mixed-media fashion illustration: expressive ink contours, graphite, dry-brush marks, selective marker fills, visible exploratory lines, sketch-like incompleteness, tactile pen pressure, and artistic paper texture. Avoid photorealism, cartoon, anime, and sterile digital graphics.

The finished poster should feel like a rare, premium silkscreen fashion-tech art print, with grained paper, slight ink bleed, natural print wear, crisp yet lively lines, collectible-quality finishing, and 8K-level detail.

Negative prompt: cheap headphones, generic headset, photorealistic studio photo, cartoon, anime, cluttered background, extra people, excessive props, low-detail face, heavy ugly fonts, large text blocks, muddy colors, celebrity likeness, weak product focus, mass-market commercial layout, low-resolution texture.
