There was one shot that took me out of the moment, that I seem to remember being discussed earlier, but perhaps it was lost in the shuffle. It is when the X-wings begin their attack on the base, and the weapon is still smoking. I had a go at fixing this:

I know this project has been finished, so I’m just leaving this here in case somebody wants to incorporate it into their own versions. 😃
