HMS Imperiuse and Warspite, anachronistic design

I have my HMS Imperiuse design for an anachronistic belted cruiser. The originals were laid down in 1881, but mine would be laid down in 1910. My design works pretty well. I am using Springsharp techniques that I learned from the Red Admiral, from Wesworld. This design has the same calibers and numbers of guns as the original, except they are of newer vintage. The dimensions and displacement is also that of the original. The resulting design is, of course, much more capable:
