Well, personally there are a few things I don't like about it.
First off, the cockpit is huge compared to the rest of the ship. And the shape of it is a bit strange as well.
As well, Renzu ships are supposed to be less 'artsy' and designed for practicality and utilitarian purpose compared with other Kusari ships. Something origional, but akin to the Homeworld ship design philosiphy that current Renzu ships use, with just enough Kusari flair to identify them as such.
My suggestions are to re-design the cockpit, and maybe add a wing structure amidships. Somewhere with some weapon hardpoints. For the Ki atleast, the wings should be fairly short and possibly swept back, to give atleast the look of a fast racing ship.
