Don't get me wrong, the renzu corp vessels are very good. I'd love to fly them, but it's the texture and the basic shapes of the vessels that always repel me when I see them. They have a place here in discovery, keep the concepts of all the ships, but pleeeeeease can we just rebuild them?
All that needs to be done is just defining the wireframe a little more; Adding a bit more detail, and retuxturing it for that Freelancerish look.
The cockpits, the way they lower down like that gives them a GMG look to it. It's a look that the Kaichou adopted and if the Garanchou get's remodeled it'll mimic the same style.
