Your new videos are good! Some great additions in there. Let me give you some technical/editing advice.

For your Mustafar confrontation:
When Anakin says, “I’m becoming more powerful than any Jedi has ever dreamed of, and I’m doing it for you. To protect you. Only my new powers can do that. Trust me.” I would suggest cutting the shot of Anakin and place it over the shot of Padme backing away, and if “trust me” doesn’t fit, just cut it. The shot feels a little odd, since Padme starts backing up, but then in that shot she isn’t moving. Either use “trust me”, or “only my new powers can do that”, but I think it would be better to just remove that shot.

I feel like there is a lot of quick cuts when Anakin and Padme notice Obi-Wan is at the top of the landing ramp. I wonder if certain shots could be removed to tighten that up a little.

The added line, “You weren’t there! I did what I had to do!” doesn’t really fit imo.

The pre-Mustafar stuff:
You cut quickly to Obi-Wan to remove Yoda calling Anakin “young”, but honestly I think you should consider keeping it in this instance because this cut is just way too quick.

I understand why you cut Obi mentioning “the death of Count Dooku” to Padme, but I think we lose some of the time we get to see of Padme as the reality of the situation slowly begins to sink in for her. It feels like the scene moves by rather quickly.

I do like how you were able to keep Obi-Wan realizing Anakin is the father. That works pretty well I think.

I don’t think it is necessary to show Obi-Wan hiding in a small room aboard Padme’s ship, because in your version she knows he is with her, right? I understand why he would need to sneak on the ship so no one else sees him, but once they’re on the ship he shouldn’t be hiding from anyone.

I’ll try to be brief but I wanted to talk a little about the characterization. I understand why you wouldn’t want to make it seem like Obi-Wan isn’t going there to kill Anakin, but by removing this, now it seems really weird that Padme claims that she brought Obi-Wan there to kill him. So she is mad and is lying to him that her and Obi came to kill him? But she just told him she loved him still, so why should she try to trigger him like that?

It just feels really out of left field for her to say that now, especially if Obi-Wan didn’t give her the impression that he might have to kill him. I also think some tension is lost if Yoda doesn’t pose that dilemma to Obi-Wan. It is similar to Yoda and Obi-Wan telling Luke that he must kill Darth Vader. There is conflict in the task Luke must face and his own morals. You get a conflict with Obi-Wan, who doesn’t want to kill Anakin, but Yoda tells him the Sith must be destroyed. The moral dilemma creates interesting drama. So I think there is some benefit to Obi-Wan telling Yoda he can’t kill Anakin, then Padme asking if he is going to kill Anakin, and Obi-Wan not knowing how to answer. Maybe when Obi-Wan and Padme go, they want to try and save Anakin, but they don’t know if they can. It provides this through line that would lead up to Padme realizing Anakin has changed and admitting they came to stop him.

Right now it feels like this.
Anakin: You brought him here to kill me!
Padme: Because of what you’ve done, what you plan to do!
Obi-Wan: Whoa, wait, that wasn’t the plan!

I think you also have this issue of removing Anakin telling Padme that he brought peace to the Republic and that they can rule the galaxy, but as soon as Padme is out cold he starts talking about his new Empire. I guesss it is supposed to be that since Padme has turned against him, he changes his focus to the Empire? I feel like it would work better with what you’re trying to do if all that talk could also be changed, because even if it is pushed back to after Anakin chokes Padme, the change is rather sudden. Based on the way you’re portraying Anakin, I feel like Anakin wouldn’t be talking like that until after Padme is dead and has lost everythng else.

I have some ideas for some of these changes but I’ll see what your thoughts are first. Again, not trying to say there is a right or wrong way to approach this. Just trying to logic through the characterizations to make sure they hold up.
