Image compare: flux2-klein vs flux2-klein

Animate the exact uploaded image into a natural romantic walking scene. The same couple slowly walks forward together inside the existing street scene, side by side, maintaining their original positions, identities, faces, hairstyles, clothing, jewelry, body proportions and illustration style. Their walking should be subtle, graceful and synchronized: natural alternating steps, gentle arm movement, slight shoulder and body movement, realistic hand movement, and very subtle movement of the woman's saree and both hairstyles. They occasionally glance lovingly toward each other while continuing to walk.
Preserve the entire original background exactly as it is: same buildings, walls, windows, flowers, hanging lights, lamps, plants, cobblestone street, colors, lighting and perspective. Do not generate, replace, remove or redesign any background elements. Keep the camera locked and stable with no camera movement, no zoom and no scene transition.
Maintain the original hand-drawn digital illustration appearance throughout the entire video. Smooth continuous motion, elegant romantic mood, realistic walking physics, natural expressions, no distortion.
