The framing isn't bad, but the camera is always so stiff and the zooms make it feel like we're watching a slideshow during some shots. They're sock puppets! Ask yourself why you chose to use sock puppets and how you can best utilize their advantages to plus your film. Make them move! Get a little goofy in the visual presentation and acting to starkly contrast the story and narration(it's a tight line to walk, but you can do it with quick cuts and close ups).
Honestly it's a little surprising that when someone finally does talk out loud on screen you decided to keep their mouth closed shut :/
