That model is shaping up very nicely, but the most glaring flaw with it is the fact that it's too similar to the existing Kusari fighters. It will need something to make it stand out from the rest of the crowd, and while textures can do that to an extent, the thing as it stands now is just too damn similar geometry wise to existing KU ships.
A good example is the Black Dragon, the Hog HF. Retains a Kusari feel while using new textures and a significantly different design.
Anyway keep at it, the mesh looks clean and it seems you've cleared up the extra polygons from earlier, so we'll see where it goes.
