I am struggling to visualize the space battleships of a human civilization which made it into space in the mid 1800s and have progressed to a level of technological development similar to that depicted in Star Wars.

I have decided that the ships would have a layout similar to that of the iconic Imperial class Star Destroyer;

Combined with the rather unique complexity of the French 1880s pre-Dreadnought battleship aesthetic;

A bit odd I know, but any help would be greatly appreciated. A simple sketch would be more than adequate, it would simply act as a starting point from which I can then build upon.
Funnels can be ignored.
