动态模糊剪影，适合抽象街头摄影

A blurred silhouette of a {argument name="subject" default="subject"} in motion, wearing {argument name="color" default="color"} sportswear, captured using a slow shutter speed to create a strong dynamic motion blur effect. The overall image should have high contrast and minimalist composition, with no logos or text appearing in the frame. The background should remain neutral and clean, with a style that is abstract and energetic. The overall feel should reference the advertising visuals of {argument name="brand" default="brand"} or the editorial style of street photography.
