What I am referring to is how the bilge keels, propeller shafts and the hull have two different colors. The hull is using a color I made up years ago, whereas the other two parts have the proper Norfolk 65-A anti-fouling paint.
Your pilot house is taken from the refitted USS Arizona, but it should look almost exactly the same as the South Dakota class. This is from Norman Friedman's book on US Battleships, it's a design from 1935, notice how the pilot house is a block, ala Colorado/South Dakota.
Here's a 1933 design:
and two 1934 designs:
The last two have a much more "cruiser" like superstructure.
I like the "test" drawing one more than the Arizona one.
Did not notice this before now, so this one's on me, the bilge keels are far too close to the bow and stern, you should move them closer together.
And if you have the patience for it, I would reccomend repainting the ship in it's proper colors. It would look better without the shipbucket gray.
