A British super destroyer for 1908

One of my ongoing interest, since the late 1960's has been super destroyers from the period starting in 1905 and beyond. I think that I had been inspired by what I had found out about the big German destroyers from late in the Great War. My 1908 design is for a British ship with 6-4in QF guns and 4-18in TT. The designed speed is 35 knots. This is the Springsharp report:

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 187.0 %
  - Above water (accommodation/working, high = better): 168.1 %
 Waterplane Area: 8,673 Square feet or 806 Square metres
