Very nice video, thanks for sharing it! May I make two suggestions?

1. Rather than shooting with the camera held up by one hand and looking through the viewfinder, wear it by the strap bandolier-style across your neck and one shoulder. Keep the back of the camera against your chest, and hold it with both hands, pushing down so that the strap is tensioned, and frame using the swing-out LCD. This technique will let you get much steadier shots with very little or no camera shake.

2. When shooting something of interest, like the swimming bear, shoot some wider establishing shots so we can get a sense of where this all taking place. I liked the actor who played the bear, by the way.
