In a way ... but the thing about most of your ships is that they either look like a big coffin, or most of their hull is composed of various shapes arranged into regular geometric shapes (like squared and octagons) along the XY plane. Plus, they are almost completely symmetrical top to bottom. The Deimos does have that general shape, but it has some vertical variation, plus some interesting curves, and a couple of engines sticking out of the bottom (the engines are complex shapes, not just simple fin like things). And that is just one ship. There are plenty of ships in FS2 (like the Hecate) that look nothing like that (well, I suppose if you strip the Hecate down enough, it could be made to resemble a long box, but it has additions to it that actually contribute to the general shape, rather than looking like they were stuck on with duct tape).
