My thought on the whole stardestroyer placement issue (during the Executor reveal) is that all the stardestroyers have all just returned from deploying the probe droids around the various systems and are now regrouping with the Executor, so they would be facing all directions and not uniform in placement

Just to add to this, maybe what you could do is begin the scene by showing them all jumbled up, but show the SDs in the background start to group together during the montage INTO a well-organized fleet heading in one direction, so when we get to the full frontal Executor shot, you can see SDs already sliding into positions around the Executor and heading in the same direction. That way the SDs are not just moving about all over the place but aren't boringly moving in the same direction right off the bat either.
