Overall an elegant shape, but I'm not too sure about the color scheme and the town windows. (Originally, I was going to rate this higher, but after seeing some of your other ships, I just realized I do like them even more than this one.)
What's the story? Is it a luxury yacht or a light cruiser? And do I see old battery-boxes for those engines?
You could probably make it a little sleeker, and give it a more unified color scheme, but overall it a good Imperial Star Destroyer-inspired ship.
I really like this build! It does need a little bit more heft underneath but... who cares. One thing you could do is snot the top of the ship so it looks less bare. On the good side, I love the greebles. the hoses are a nice touch and the (for lack of a better descriptor) green R2 heads! I am really impressed overall with this ship. Nice work. Later ~ Chris.
I agree with Ben, but I have two porblems...you only used about 2/3 of the top [the 1/3 is just plain bricks, doesn't look very good] and it could use some more bulk on the bottom...bigger ships [like yours] need have a curviture in the bottom section to make them have a sleeker, more aero-dynamic feel. Still a nice ship, I'd love to see some more of those beauts you've built!
