The GB/CS/1915 scout cruiser in Springsharp

I have a photoart piece showing Cliff's British scout cruiser design GB/CS/1915, so I thought I would try Springsharp to see if I could get a better result. The dimensions were 405ft x 41ft x 14ft, with a normal displacement of 3,200 tons. The armament was 4-6in QF guns with 4-21in TT. There was no protection except gun shields and splinter protection on the bridge structure. The intended power was 40,000 SHP with a desired speed of 32 knots. The machinery is built to destroyer standards, and the vessel is very much like a large destroyer with cruiser guns. This is the Springsharp report:
