Welcome aboard Darth Venom, it's always interesting to see the different point-of-views on certain aspects.
For myself, I thought the 'camera shake' effect inside the Stardestroyer bridge was a really neat addition, and effectively done. While it's a new and visually-'stylistic' look to the shot, I definitely like what it adds to the scene.
And while I came across a similar point made elsewhere about the 'debris' motion caused by the TIE laserblasts, it's not something that bothered me personally. But your point is certainly valid in terms of assuming there's no gravity around that huge asteroid. On the other hand I wouldn't have been sorry to see the 'orange glow' of the 'tiny asteroid colliding inside the pocket of the large asteroid' shot replaced with a small spray of 'debris' instead...but I also appreciate that adywan perhaps looks on *that* as an iconic, visually-'stylistic' moment in the asteroid sequence, too. And there's no sound in space either, which is another dramatically-'stylistic' choice at the end of the day, where these movies are concerned...and thankfully so.
While there's been differing views over many things over the years on this lengthy thread, I've noticed a creeping impatience among some lately over anyone that still brings certain things up. That's understandable at this late stage of 'ESB:R', but adywan has always seemed opened-minded to *all* opinions posted here (at least the respectfully-worded ones, of course) about even the slightest details that some would like to discuss...and I'm sure that will continue throughout the rest of this project until he announces he's done, *whatever* his own preferences are.
