I kind of don’t want a full shot of the Dreadnought and to save the ‘reveal’ for TLJ
You could crop out the right side of that arrival shot. Depending on how tight you do it, you could have a smallish Destroyer on screen in the upper left corner and then see a chunk of huge ship just pop into frame. Then it pans down to the (left) cannon dropping into firing position. Nice it have in one shot.
Cropping it (and maybe horizontally flipping it as well) saves the wide shot original for TLJ. Here you can see it’s something big, but you don’t get HOW big.
Plus it takes care of your ‘rings of DQar’ problem too.
Just a thought!
