Cinematic Motion Blur Silhouette Portrait

Generate a cinematic dynamic motion blur portrait based on a specific theme. The subject, a quiet side profile or half-body silhouette, holds the primary visual weight with subtle recognizable facial details. The body and hair are stretched into long horizontal motion blurs like light bands passing through the subject and blending into the background, as if being swept away by speed, memory, or information flow. The background is a high-brightness, clear, and soft air field without complex scenery. Colors are extracted from the theme's material, emotion, and narrative temperature, maintaining a balance between bright cool base tones, deep shadows, and a few high-saturation glowing accents. Lighting is soft and diffused with a slight film grain and lens blur. Minimal information density allows the sense of speed to breathe. Text is integrated as a visual structural element using pure white modern sans-serif fonts, with a large core word placed near the center of gravity and smaller compact phrases following a centered rhythm.
