I like your first ship and your flagship. Try reducing weapon spam by using modded weapons.
Also move the weapons into the hull more, They can be easily shot off by enemy fire and its not very appeasing.
Ship I've been working on today. I think it came out pretty good. And yes its named after the ship from the Halo Book, First Strike .

I like the Advanced Alien Obstructor. You might want to shrink the Gat Blasters, they seem a bit to big for the ship.
The colors are ok. But I'm not a fan of them.
You might want to go easy on the boosters and simply mod the guns.
