3D动画喜剧短片：快闪掩护

Fast, expressive cinematic 3D animation, visual comedy, exaggerated facial reactions, strong character acting, dynamic tracking shots, quick cuts, escalating physical choreography, realistic city environment, bright appealing lighting. The comedy must be immediately understandable without dialogue. IMPORTANT: The first mistaken wave must be extremely clear. The audience must understand that the stranger was waving at someone behind the man. Every subsequent action must clearly come from the man's attempt to hide his embarrassment. Do not make the crowd appear randomly. Show one person copying him first, then another, then several people. No dialogue. No text. No subtitles. No logos. No watermarks. No copyrighted characters. No celebrity likenesses. No violence, no injuries, no explosions, no surreal transformations, no random chaos.
