Umm...you might want to get the Descent Manager package and use ModelView32 to have a look at those models.
http://www.descent-network.com/descman/ - Go get it. You can pan and zoom and rotate to your hearts content.
My intention is to build an ORION CLASS Capital ship just like any one of the 3 nameplates in Free space.
So your building a high detail version of the ship from the game? In that case you've got some serious stuff that needs to be worked on. This has nothing to do with "individual interpretation" or any lack of material.
Lets compare:

Your render.

A render from Volition of the model in the game.
You've got the ship upside down for starters. I see the main basic shapes are there, but if this is to be a high detail replication, then the proportions also need to be the same which they are not.
I'm trying to build a real model here not a make believe one with a few cleaver drawings.
Yours is just as makebelieve as Volition's. Your aspiring to make a highly detailed version of the Orion destroyer or at least thats what you said. I think its commendable to take on such a project, but if your going to do it, get some of the essentials down.
And im only arguing this to your benefit, no insult or harm intended.
