The 1903 Battleship-Cruiser with superfiring guns

I was looking at my photo of the GB/BB/1903 battleship-cruiser and was dissatisfied with the version that had guns in echelon. I decided to see what could be done with superfiring turrets. I did slightly lengthen the ship as well as change the gun layout. The result was very much to my liking:
