You are right, she is high. But also beamy and to let the light in towards the centre of the yacht, the ceilings have to be higher than on a smaller yacht.
I made a grid with 3m (10 feet) for each floor which is pretty normal for a yacht this size. Here you have the entire history of the concept from the first line to the finished profile.
As you can see, she was a little more aggressive from the beginning to finally grow from 165 m to 170 m, with the superstructure more centered over the hull. The resemblance with a war ship is of course to make her a little imposing. Maybe will keep pirates on a distance too?
