Yeah, then you'd see how far advanced our models are compared to the CGI versions of the original.
Really, while the polycount was a concern for the capships(I've seen the original sketeches for some of the ships-lots of smaller detils are missing, though the general shape is the same as on the drawings) It's didn't matter for the fighters. They could've made more advanced fighter with lot's of greebles and details, but they choose to go for rugged industrial and simple looking style for the ships.
And as lars said, it looks more 'realistic' if the ships have homogenous surfaces instead instead being covered by lots of different tiles and having areas open to space with wirings and techstuff and all that.
But true, I could've added some more details, but this is one of my earlier attempts at rebuilding the Kilrathi cap ships so it has a bit lower details than the others, though it still looks mucho better than the original IMO.
