クロマティック・モーション・ポートレート旅行写真

Create a vertical before-and-after travel portrait image: the top half fully preserves the pose, clothing, facial features, and environmental composition of the input real photo; a thin white divider line in the middle. The bottom half reinterprets the same scene as a colorful dynamic oil painting/wet canvas smearing effect: the face, gestures, and body contours remain recognizable, while continuous horizontal color bands and semi-transparent brushstrokes are pulled along the subject's motion direction in the remaining areas; use teal or blue-green as the base, combined with warm tones like orange-red, coral, and cream yellow to convey speed and air flow. Preserve key light-dark and spatial relationships, using oil paint grain, slight defocus, and edge melting; do not add extra people, do not completely erase the subject, and do not use simple radial blur or filters. No text, logos, watermarks, or corner marks allowed.
