The expanded opening scene is not really how it’s meant to play out.
It’s part of the probe droid scene outside the base.
A few things get shifted about like the probe droid scene near the shield generator comes before the shots inside the command center with riekan. They are meant to be listening to an outpost gun turret radio transmission when it get’s cut off.
Then the scene with the probe droid destroying the gun turret as you have but with the cut music and sound effect.
Next come a shot of snowspeeders.
Than Han and chewie face off against the probe droid.
I like your work though looks good the Luke training scene. Keep it up.
I can send you a video about the probe droid sequence.

There are quite a few missing Special effects shots in Empire and a whole deleted gun battle between Bespin guards and the Stormtroopers although it is unclear if it was ever put on film but it is in the script.
You should try to find the music spotting score to footage for the Asteroid chase so many shots missing…
Found it for you

This is the footage put to how the music was scored to the film with black for the blanks. In fact this is more outlandish than anything I ever thought was missing but I knew it had stuff missing.
Using the music score as a guide I identified the following.
The snowspeeders are shown taking off out of Echo base
The falcon is shown lifting off and the Doors were to also open just in time
Space slug sequence slightly in wrong order “Cave Collapsing POV cockpit shot missing”
Falcon is shown flying towards Bespin in Space from the Iris Wipe then that flows into a drop through the clouds to the shot in the film.
music wrong on rescueing luke from under cloud city and Lando saving Luke missing.
Also When Luke crashes in the Swawp it was meant to cut to R2-D2 complaining on the subtitle readout whilst luke say’s “how you doing back there?” or something like that. More Buddy movie it comes off a bit weird the way it’s cut in the film. That is in the script too.
There is a good few videos on my channel that can help you out a bit… You decide but you can use the audio and copy any edits if you choose to.
The Wampa attack on Echo Base looks like one of those scenes that will be like a black hole…I’d personally save my sanity on that one 😃
Hope that helps.
