An admech cruiser? Looks like a ship's spine, looks about the right height for imperial, and the gap between the two batteries would make it admech, or just a funky imperial ship?
I absolutely love the spine above the engines. As for recent changes, the small turrets around the bridge have done wonders.
I have a question about the new launch bays - will you have the openings in the front/rear facing bits, in the side, or in all three?
Also, I kinda want one of there, despite not actually having a marine fleet. Hum.
