A pretty conventional, if large, 1916 British battleship-cruiser

I was looking at the Queen Victoria class page, and thought about my 1912 design for a battleship-cruiser. The next obvious step would be to design a 1916 battleship-cruiser. The layout is pretty conventional with 8-16in guns in twin turrets in the usual arrangement. The secondary battery is 16-5.5in QF guns. I am not looking for extreme speeds (in this case), but I wanted an advance over the 1912 ships. I chose a maximum speed of 29 knots. As usual, the ships are large. The armour basis is 14in, so the design is well-protected. This is the Springsharp report:
