The wrong trousers storyboard

A scan from the book 'Cracking Animation, The Aardman Book of 3D Animation.'
I think its interesting to look at professional storyboards, and take into account the style in which it is communicated. This storyboard isn't overloaded with text, its basic and informative. In this scene there is a lot of sudden movements, this is shown using these sort of cross hatched lines, informing you of the movement of the character or object.
