Stylistically, you've kinda got a liberty feel going on, a lot of the kusarian ships use triangular shapes, with points being the theme over cuboid shapes. If you were to stick to the style, I'd say you have a ton of room for detail (assuming that's what you meant by alpha version) I also feel like it's not round enough, but that's not necessarily set in stone for kusari ships.
As far as any other feedback I could give, I'd suggest being a bit more expressive with the tail engines. They dont really deliver a message of power.
