Great job! I love all 3 of 'em!
Edit: Can't wait to see the finished liner
The GB looks almost identical with the AT, and that's more along the Coalition's line of thinking with modular ships.
I think the GB should be modeled more after CTE's combat ship line such as the Eagle or Roc.
The old Spatial VHF could be a good basis from which to build the CTE GB:

Utilitarian design is nothing uncommon, and I've already submitted it.
I love the design and the fact that some of these are submitted is super exciting. I cannot wait to fly them!
