I know, the exposed cargo containers on the current whale model are increasing the poly count of the model quite a lot, but it is still more unique looking, than the streamlined proposition of yours.
The current Zoner transport and cap ship line doesn't really need a total design overhaul. A clean up to get rid of some unnecessary details to reduce the poly count and a material overhaul would be enough.
Although the current carrier model seems nicely textured.
The first Zoner destroyer I made was a horrible model by quality. The current model is of far better quality. Yet it kept the design in general which always resembled the first Zoner cap ship in the mod: The Munificient class frigate from the Star Wars prequels. We got rid of the Munificient model, but back then and now I still think the design fits the Zoners perfectly. Rough, but tough and different as the Zoners themselves. The streamlined design does not remind me of Zoners.
