I really like how you piled up gradually from the body to the viewing deck. for anybody who wants to know, there are black star destroyers, but only a few in existence. they are eclipse class and the biggest of all. again, great job.
WOW! Thats awesome I love the black theme I in fact, have a lego that is normally white but I made one in black colors like yours, it's called Imperial LAAT/i Gunship, please check it out when you have time!
