Ok I am going to come clean I am confused by it...

But I started looking at it more in depth now.

a few things to note

1. The lights are on/off in the tunnel that Leia runs down

2. Red Glow is missing from pillar which leia takes cover behind (assuming you keep SE windows)

3. Window frame missing off to right of Leia's shoulder (assuming you keep SE Windows again)

4. Millennium falcon could perhaps bee seen out of window when Lando pulls Leia away depending on how you want to interpret it.

Ok I am less confused The storm troopers on leia side seem to be emerging from the wrong direction and chewie also shoots one of the storm troopers that leia should shoot because he comes from the same stairwell that leia is fighting them from behind the pillar.

R2-D2 is correct apart from we should see a glimpse of him going out of frame when leia runs for it.

That is my interpretation anyhow and I don't claim for 1 second to be right it is very confusing but I think It makes more sense now but the music is messed up a bit.
