A beautiful ship, indeed, I quite like it.
Btw, the light AA gun you've replaced the aft FC with is a fictional 37mm gun I made for an AU of mine a while back, so it wouldn't really be mounted on a British ship, considering they used the Pom-pom and later the Bofors 40mm/60 M/36 IRL. While I'm partly flattered that you've nicked one of my old guns(
), I'd say it's better if you keep to real life RN equipment if you're making RN designs.
