The Naboo ships, boats and speeders are an interesting look but not for Naboo.
That style matches the crystal spires of Coruscant better.
The only independent state we see in the OT is Bespin and the pod cars, the guard uniforms and weapons and the interiors all match the design of the city.
There is no reason I can think of why the Queen couldn't fly a marble spaceship covered in statues which has interiors like the buildings on the planet. It's a ceremonial craft and it would match the elaborate clothing the Queen wears.
Indeed her Royal Spaceforce could fly marble fighters too.
Lynch screwed up with Dune in many ways but one thing that you can't level at his film is boring derivative and inconsistent design.
The problem with the PT isn't that it doesn't look the OT more than design has no rhyme or reason to it.
If you look at the big ships of the golden age of exploration they were often highly carved and decorative and matched wooden buildings of the same period.
The carving on a ship would match a carving on the beams of a pub.
If you look at a cruise ship now it matches much of the curves and materials of a car or even a block of flats.
Some people scoffed at Vincent Ward's Alien 3 idea of a wooden space station.
The Star Wars galaxy has much more elaborate technology than the Alien universe so there is not reason for ships to be made of metal and look like modern fighters beyond the expense.
A royal flight that presumably hasn't seen action for hundreds if not thousands of years of peace within the Republic could look like anything.
I would much rather see how a carved polished marble starfigher breaks up in a dogfight than another metal ship.
Making TPM resemble the OT at all was probably more of a mistake than making it look different. The Clone Wars is a different issue. There I could see it beginning to look more like the OT and to some extent it does.
Ultimately who cares what the Queen's ship is like when the whole crew are a bunch of planks?
