界面稿 GPT Image 2 提示词：Weathered Custom Cub Concept Bike

A highly detailed concept illustration of a customized vintage step-through motorcycle inspired by a Honda Super Cub, shown in a clean studio-like three-quarter left side view on a plain light gray background. The bike has a rugged post-apocalyptic street-build aesthetic with a black, white, and muted gray color scheme accented by small pink stickers and decals. Emphasize heavy weathering: chipped paint, scratches, oil stains, grime, rust flecks, ink splatter, worn edges, and layered sticker residue across the entire body. The front has 1 square headlight with an X-shaped light pattern and 2 smaller stacked auxiliary lights beneath it. Use spoked wheels, thick all-terrain tires, visible front suspension, exposed mechanical detail, chain drive, and a sturdy center stand touching the ground. The leg shield and side panels are covered in graphic decals, Japanese-style warning labels, numbers, symbols, and distressed typography, including a bold large kanji mark on the front fairing. Add 2 hard side cargo boxes on the rear, one larger box on the far side and 1 nearer black box with extra stickers, plus 1 hanging vertical tag charm attached near the rear case. Include 1 long black ribbed seat, rear rack framing, exposed wiring, metal brackets, bolts, and compact utility accessories that make it feel hand-modified and functional. Render it like an industrial design sketch mixed with polished anime mech concept art: precise linework, watercolor wash shadows, soft gray ground shadow, high-detail mechanical realism, slightly messy inked edges, and a collectible custom-bike illustration feel.
