Replace “seamless warm light-gray background” with “deep charcoal studio background with a subtle gradient,” and change “soft slightly directional studio lighting” to “dramatic hard side-lighting with controlled rim light.” Keep “crisp, realistic reflections” to preserve the product-render clarity while increasing contrast.

Replace “teal accent wheels and a matching teal roof accent stripe” with “bright saturated teal wheels, illuminated teal roof accent stripe, and subtle teal light accents along the front fascia.” You can also change “subtle silver mid-panel highlights” to “high-contrast silver mid-panel highlights” so the accent colors separate more clearly from the dark body.

Keep the fixed visual language, including “photorealistic studio product render aesthetic,” “seamless warm light-gray background,” “soft slightly directional lighting with crisp reflections,” and “side profile product framing.” Replace only “compact futuristic concept van” with variants such as “compact futuristic delivery van,” “sporty electric city coupe,” or “small autonomous shuttle,” while preserving “matte dark gray body,” “black lower trim,” and the teal accent treatment for continuity.
