To be fair, the period following WW1 was a very confusing one with lots of different capital ship designs being bandied about. If you aren't aware of this it's easy to get things wrong. The MM995 design is more elegant and traditional than the actual 1921 G3 design but in fact the RN at this time was being quite innovative. Grouping all the main armament ahead of the machinery spaces allowed for a more effective distribution of armour and as the Navy's policy was always to attack, the lack of heavy guns which could fire dead astern was not seen as a disadvantage.
