Doesn't really look like it belongs in space, imo. The rules of ship design that apply in a wet navy have absolutely no bearing in space. While you might be able to take some design cues and use them, you can't design something that would look at home in the water and say it belongs in space.
Also, those guns look ridiculously long and large, completely out of proportion. They also, being designed from a "wet navy" perspective, don't cover the bottom of the ship.
Also, 33 knots, while being a reasonable number on the surface, is uselessly slow in space.
It looks like you started from a cartoon sketch of a wet navy battleship rather than actual pictures.
