I see what you mean about the windows..maybe a bump map to make them look a little recessed? Maybe a little external glow around the edges? They look a little like they've been painted on. The model and texturing is gorgeous. I love the panelling, even without the windows it just looks ginormous. You've really done justice to a beautiful set of deckplans.
The ship just looks really credible. Everything on it looks like it has a design purpose. The globules (bunkers? fuel tanks?) running down the spine just make the ship for me, as does the asymmetry.
Great set of plans by Mikazoid and beautifully rendered. My only one very small crit are the barrels on the guns, they look (to me) a little too large and out of scale which kind of jars with the rest of the vessel.
Thanks for posting Andrew, beautiful work.
