Odd, the only thing that's a bit different than the previous was the more pointed "saucer" as opposed to the half moons they usually use.
An explorer type vessel, roughly Excelsior sized. I enlarged the "saucer" a great deal on this one. It's about five decks thick now. The body is intentionally narrower as well. I tried to make it a little less compact and solid like you expect from most Cardie ships. It's trying to provide a more peaceful appearance.
Light cruiser, I stretched out the front extension and shrunk the "cobra head" down to just a small pair of fins.
Heavy Cruiser, somewhat in the vein of the first destroyer I posted. Like that one I was going for a very solid, very strongly built design. The "saucer" is a lot like the Hideki's being more croissant than frisbee shaped. It's thick in the middle, almost wedged shaped before cutting out in the back sharply.
