To help with this I have been watching the Chase scene in ratatouille
(sorry for the odd Audio this was the best i could find on youtube to show you watch i was watching on my DVD)
From watching this I notist that the shots are normally further away to help the watcher know where the character is. and the Camera kept focusing on the Window exit to keep reminding you what his goal was and where he wanted to go, as well as showing you how much progress he had made running and how long he had till freedom.
Hopefully this will help greatly in my Re-draft of my storyboards, i am also hoping to do a floor plan at a latter date to help with the lay out and directions my character will be running in the store.
