A nice version of the GB/CB/1941 design

I tried a new version of the GB/CB/1941 design in Springsharp 3.0b1 Beta. The design turned out very well. This is a 31 knot ship that has 9-16in/45, 20-4.5in DP, and 42-40mm AA guns. The armour basis is 12in with a 5in deck. The speed is 31 knots. The ship is somewhat like an updated Hood, with 16in guns. I probably should have some miscellaneous weights, but I am not sure how large they should be, for the aircraft capability. I would welcome some suggestions. This is the photo of the pencil drawing:
