Aalenfae, that's a great rough cut! I've always wanted to edit the elevator scene so that as the ship levels out, the three of them simply fall into an open doorway, because I'm not a fan of the miracle grappling hooks. That always left the problem of how to show Obi-Wan waking up, and left the cringe worthy ray shield scene. This ingeniously circumvents both of those events!
I noticed you put in some non existent dialogue subs for Grievous towards the end, so I'm assuming you're planning on redubbing Grievous' voice? If so, I would go even further to say, if possible, rework the entire conversation between him and the heroes to make his banter with them fit better with their responses.
Either way, great work!
