Firstly, change the name - Terran Pride has been done by Setekh a while ago and there are plent of other names that could do http://www.fattonys.com/images/terranpride3.jpg
Is most likely the best of them all, the bright one is way
to bright. The dark one is only slightly darker than the terranpride3.jpg version.
Is the Iceni ramming the Orion, or is that Orion model seriously ****ed? If it's ramming you need some explosions and fire and stuff going on in that area so it doesn't just look like the model is broken.
Aside from that it's looking pretty good - I like the layout and everything. You might want to put some lighting on there? (since the sun is in the background the ships we can see should be dark on our side and light around the edges).
