I've watched up until the end of the Barge fight and I thought contribute a few observations while they are fresh in my memory.
I have to agree with Ryan, the squished shots must go they really do detract from the ideas on display here.
I think you could have more ROTJ dialogue in that opening from the Emperor's arrival in the theatrical version.
PALPATINE : Rise my friend. I sense you wish to continue your search for young Skywalker?
VADER : Yes my master.
PALPATINE : Go to the Death Star and await him.
VADER: He will come to me?
PALPATINE : His compassion for you will be his undoing. He has grown strong. Only together can we turn him to the Dark Side of the Force.
VADER: Yes my master.
These lines are practically said twice in the same picture it makes more sense to condense them into one conversation and have it at the beginning as it sets out what the Emperor has in mind for Luke and leads to Luke on Dagobah.
I wish there was a way to replace Yoda repeating his first lesson to Luke (which turn out to be inaccurate) with ...
YODA : Death is a natural part of life. Rejoice for those who transform into the Force. Mourn them not, miss them not.
It was such a great line that it seems better served in ROTJ.
I don't know if it possible to swap some of the furniture around the three Jabba thone room entrances.
Boushh is meant to be a bounty hunter presenting a quarry to the Hutt so why then the aggressive resistance to 'his' entrance?
Luke is meant to be an unwelcome visitor and yet he is only briefly stopped by two guards.
It makes Jabba look weak if people are breaking into his fortress willy nilly.
I don't know if it's possible to take more material from the current entrance of the droids and mix it with Luke's entrance to create a calm entrance of Boushh and Chewie with Oola still alive.
Threepio and Artoo could then turn up with Leia chained to Jabba in a party mood (Han, Leia and Chewie are now his guests he has something to celebrate). Leia can see Oola die which makes her position all the more uncomfortable.
Luke could then turn up and be met with futile resistance (which makes Luke seem more powerful and aggressive).
I appreciate this is a lot of hard work moving Threepio, Leia and Oola around but it would build on the sterling work building the mood of the opening.
The saber building and Vader communicating with Luke telepathically aren't really adding anything, indeed showing Vader arriving at the Death Star is made surplus to requirements now that we have met him at Coruscant. All we learn is that the Emperor is arriving soon and we learn that at the Rebel Briefing.
It's a real achievement so far and I'm really enjoying what you have done.
The tone is much more serious and in keeping with the end of ESB.
Luke is fully trained but has lost his mentor and all of his friends are trapped.
He himself is being plotted against.
Fett is not missed. I forgot he had been cut to be honest.
