One thing I'm thinking that might help the tension of the retracting steps scene is to show the impaled soldiers at the bottom right after we hear the stairs start to retract. From what I recall, the official KOTCS doesn't show the impaled people until everyone is safely on the ground. If my memory is correct, that was a pretty stupid editing choice.
On a completely different note, my mounted RotLA poster for my theater room just came in today. It looks awesome! I'm psyched!
