Hey Adi, just checked all the changes in page one and this caught my eyes :

9. Fixing it so the hanger doors only close once.

There's one other thing you could fix here (if you haven't already in which case I apologise for this useless reply :D ) :

Right after those doors have been closed Chewie howls and leans his head on the ladder, as shown below.

In the next scene 3PO tells R2 that Luke will be alright and yadda yadda, and THEN you can see Chewie leaning his head again, just as he did one minute before.

So... Is this a continuity mistake or is it just me?
