The VFW engineering drones and our secretive order of shipsmiths have offered the following suggestions. These are by no means definitive and you may disregard any or all of them.
1) Main turret coverage: Your ship lacks any forward underside turrets. We\'re assuming this ship is designed to engage via broadside (rather than head-on like VFW designs), so the lack of underside turrets isn\'t crippling, but it does present an obvious blind spot that might be exploited.
Recommendations: A) Relocate the underside rear turret to a more central location where it can cover fore/aft and port/starbord. B) Ensure there are enough smaller defensive gun emplacements in that are to discourage exploitation by smaller craft.
2) Sponsons. You have a nice, smooth, vaguely cetacean hull here. Rather than breaking up its pleasing profile by cutting flat areas out of it as gun mounts, additional armament can be placed on small extentions that protrude horizontally out of the hull. These offer the weapons mounted on them a wide arc of fire and ensure that a castrophic failure on their part doesn\'t leave hole in the primary hull. Our own Nocturne features four defensive turrets on small sponsons near the nose if you\'d like a visual example.
3) Texturing. Though entirely nit-picky and not at all necessary, the flat, boxy areas that link the curved forward hull to the cylindrical base of the drive section are great places to add some interesting detail work. Rather than a simple paint job, it seems a nice area to add some vents, tubing, light turret sponsons, or some rounded armor plates. Something visually interesting, either way.
That\'s all they have offered other than some general grumbles about why they aren\'t allowed to make ships like that
Silly shipsmiths.
