In combat, not having any exposed parts sticking out for your enemy to hit is an amazingly good method for staying alive.
Without an exposed 'conning tower' and a wide streamlined shape, this ship provides an excellent silhouette and battle profile. Clarification on this point would be nice. Otherwise, I would guess this to be a 'forward bridge' or an 'operations bridge' as opposed to a 'battle bridge' which would buried under layers of armor and super-structure. If the bridge is not located further inside the ship, I would assume this to be the actual bridge. In the close-up of the front-dorsal area, I can see a semi-circular piece near the top of the exposed face. Also, if the depression angle on the guns is high enough, then all of them could be fired at a target above the ship at the same time, allowing for devastating alpha-strikes. By consolidating the primary weapons to the top-dorsal area, you have made it easier for the commander of this ship to focus all available firepower into a single target and protect the rest of the ship with large stretches of uninterrupted armor plating. I have carefully studied all of the different profile views of this ship you have created and am prepared to give you my critique.
