Looks like a neat ship; some of the back section seems a bit cluttered, but I like it for being Minifig scale (is it actually possible to place a Minifig in the "bridge" module on top, too? Judging from its size, I'd presume that it should be (?)) and for the colour scheme. I think, the different shades of blue and the green for the decorations go well with an overall white ship.
This is a very nice ship, I like the color scheme and design. :)
However you can't call it 200 meteres long while it's got minifigs in it. If you want to say a ship is 200 meteres long you should build it as a mini scale ship.
You should add some pics of the interior too.
