I really like the front 4/5ths of the ship.
Also, I think the civilian ship per warship rule means per faction, not per designer. You'd have to make another Civilian KFY or Geshrinari ship to counterbalance this one, as the hidden sun clan is not part of Yamatai.
In the description, "Aft is the drive section with four massive Turbo Aether Plasma visible." is missing something. Turbo Aether Plasma whats?
Where it lists which type of ships it can fit, could you add a number of how many of each class can be effectively fit into the bays?
aside from that, it looks pretty good.
