Here’s a version with only the Star Destroyer emerging from the clouds:

It would be awesome if the destroyer blows up a transport, so that Finn has a loud noise to react to and his line ‘they did it’ would make sense. I would bet that all we need is a transport taking off in the distance at the beginning of the panning shot where Rey is running from the castle - the one that begins on the castle and ends on the woods. We would only need to notice the ship taking off, and the destruction would happen offscreen, with Finn reacting to the noise and looking up. Then there would only need to be a cloud of debris for that shot. No need for TIE fighters, the shuttle, any of that.

Done and done.
