Snoke getting himself projected extra large would certainly be in character for a megalomaniac ruler, user of the Dark Side or not.

In review threads, I have also seen a complains about the spaceships being ugly: especially the boxy Stormtrooper landing crafts and the craft
that Leia arrives in at Maz’s castle. A space ship in Star Wars should have large engines. Opinions I have seen have been mixed about Kylo Ren’s shuttle.
I think, if possible, the landing crafts could be augmented/replaced with new CGI of a craft more reminiscent of the Sentinel-class landing craft first seen in Shadows of the Empire and then in ANH-SE. The Sentinel-class is somewhat similar to the Lambda shuttle but smaller: the middle part is a box like the boxy landing craft in the movie - rotated 90 degrees so that the ramp is on the side. Cockpit to the left of the ramp, engines and folding wings to the right and a large fin on top of the box.
Alternatively, use reminiscent craft that carry the trooper-boxes underneath, dropping them when they are not far from the ground.
