About this creation
if you hadn't already guessed, the design of the Executor is loosely based around that of LEGO set 6211 (although its over twice the size) - 2 were used in the vessel's construction, in addition to around a decade and a half of random other sets.
If i'm understanding your quiestion correctly, only the Imperial class star destroyer, set 6211, is not of my own design. I just threw her in there for the sake of comparison - that's not exactly a small ship, but it's dwarfed by the Executor.
