Oh my gosh, when inspected closely this ship's hull shows such a great level of attention to detail! - You achieved so very nice shapes at so many places, like it was precision-engineered. Very high construction quality everywhere. Some of the "functional decoration", like some tanks and some sort of reactors are very nicely designed.
I also see you use a lot of the same kind of 3x3 pipes that I used on some of my stuff, great job with those, they really make things look a little more "alive", they're like the veins of the ship. Some of those huge turrets look pretty amazing too, although I didn't try them to see their firepower.
All in all, this is a glorious starship, have fun if you intend to finish the interior! :)
