My Idea was to enlarge the outer frame of the windows - as these we're wooden panels that could be removed for making place for gunnery in battle.
For proportional design:
And keep the hight and breadth in the middle of the single screen of window balanced to the real windows in the back. I would do it with a pair of campasses - copying the starboard side for the starboard quater gallery ins the port one for the portside.
What do you say, Christian?
So the proportiones are still the same - hopefully. And hopefully this does some help to you.
...or to update it to 16, too. I do think the 16 windows do give the impression of a bigger window - and the illusion of giving more light into the room and a smaller fragmented more baroque looking part. What do you think does look better in your opinion?
