It's too bulky, yes. It's also too curvy for Kusari... too sleek. I know, most of the time we think of Kusari as curvy and sleek, but look at the Battleship. It's squarish, angular, but still manages to be elegant. This design, however, is almost Libertonian in the curves.
It also needs wings. The Destroyer doesn't have wings, but it's the only Vanilla ship that doesn't. The Battleship does, and I'd say this certainly does.
