A 7-10 second closing clip for AI border collie Congcong, maintaining consistency with the opening style. Congcong (still wearing its signature blue knitted scarf) stands on the same sunlit green lawn, facing the camera. It first wags its fluffy tail more briskly, then takes a gentle step forward, nuzzles the camera lens lightly (simulating a "goodbye nudge"), and finally sits down, tilts its head with a soft smile-like expression, and waves one front paw slowly (a cute "see you next time" gesture). Lighting: Warm, golden-hour glow (softer than the opening, adding a cozy closing vibe) that accentuates the smooth fur texture. Camera: Static medium shot (frames Congcong’s full body to show the waving action clearly), steady and calm. Video style: Realistic, warm-toned, 4K resolution, 60fps. Overlay text (appears 3 seconds into the clip, soft white font with subtle shadow, centered): "Thanks for your support! See you next time~" Audio: Gentle, upbeat yet mellow background music (continues the opening’s acoustic guitar + piano style but with a softer tempo, 100BPM) + Congcong’s soft whimper (friendly and warm, not loud) that fades out slowly. No other objects/humans; focus remains on Congcong’s endearing interaction and the gratitude message.
