Well, the ship looks awesome, but your poly count is way off. You need to triangulate the model before you can get an accurate poly count for in game.
Right now it is set up in quads. So this thing is probably closer to 9.6k poly count.
I really think the gigantic windows should be trimmed down. Or put more windows in them. I would suggest two or three rows instead of one.
The portion that looks like a bridge (I understand you are not using it as a bridge, but most people are going to see it as a bridge, since all the other order caps use the dome as one) is also lower then the hall pieces in front of it. Now generally for space LOS isn't required but freelancer tends to favor ships that have a bridge that is able to look in front of the ship.
