You can continue with this one. Firstly, the rudder is too far aft, and remove the torpedo bulges, she didnt recieve them until her refit in 1931-1933. Also she was commisioned with hull mounted guns, ony the Mississippi was completed without them. You should also reduce the shading on the funnel and the barbettes.
She does seem, from dry dock photos, to have a tapered armor belt http://www.navsource.org/archives/01/014000g.jpg
I'll get rid of the bulge and see how the belt looks . . . I hate bulges anyway, look what it did to the Tennessee; a beautifull lady turned ugly and fat.
