My version of the "Queen Victoria" class
I was originally inspired to try my had at photoart by the Queen Victoria Class Battleship page. I like the basic concept for the design: a more heavily armed and protected version of the Queen Elizabeth class that sacrifices some speed to achieve those goals. When we realize that the actual Queen Elizabeth class ships underperformed, so that they only could reach 23.5 to 24 knots, the sacrifice is pretty minimal. This is my version of the design. There are really only minimal differences. I would retain the plow bow, for example:
