I did some error pics for Bespin escape to make things more clear

I know you are aware of the no sparks or smoke Ady when this storm trooper get's shot... But the other thing to perhaps note is the sudden cut to the sound of the distressed crowd... Perhaps some screams in the background would help carry the sense that chewie is still in the same area or close by to Lando and Leia.

Errors

Another error When Leia Runs for the door the Lights are also off as they used the same set... And on that shot of Leia running is where the other interpretation can come from and it get's interesting.

The Way it is in the original... In this instance storm troopers to be correctly mirrored should be coming from Right to left to create the funnel effect of fighting on 2 fronts

The other way to see it is that they are fighting Storm Troopers on only one side... In Which case only this shot would need flipping and perhaps Leia taking cover and being pulled away but a more comprehensively doctored up to make sense...

So far as Chewie shooting the storm trooper coming down the stairs is concerned I think this is an editing goof.. Chewie cannot see the stairs from where he is standing only Leia can... So to keep continuity Perhaps the backround could be altered i.e. remove the stairs to make this work as chewie correctly shoots a storm trooper in view of what he can see?

Not sure how you will approach this or if you even see it as a problem but I thought I would do a more clear explanation of the scene and however you decide to interpret it there is no right or wrong just different interpretations but I hope you do agree that there is issues with it?

And it's obviously not your fault... Just trying to get this scene working much better than it currently stands in the movie.
