Nice work. 
Though I do spy a few errors here and there...
The largest one is the model is flipped around in a few dimensions. The fighterbay is supposed to be on the lower front or right (depending on how you define it, basically on the bottom). And speaking of the fighterbay, some of the ribs you added are extend too far out and just hover in space.
And some of your platform side docking points are oriented wrong. Instead of parallel to the platform, ships will dock perpendicular with it, which can make it impossible to dock realistically with.
Thanks , the docking points where aligned as I've gotten the model imported in the first place.
As for teh fighterbay ribs : Yeah I know that , thats why I made it so , thought it would look cool.
It only has like 15k polys, that is not to much is it?
The model in total has around 26k~ polys and 4 LODs the first L0D is on around 8k ( not counting the turrets with it ) the second 6k , third 4k and forth 3k~ ( I could probable educe even more but I didn't notice much even when I tested it out by staging a battle around it.
( 8 wings of fighters several cruisers and one corvette ).
Soo no I don't think it's too much. but anyway
