In image #1, there is no third buttress on either side at the expected location. In image #2, a third buttress exists on the side shown, but it has been moved further along the wall. In image #3, three windows are shown, regularly spaced, suggesting that there should indeed be buttresses between them at a similar spacing. However, image #3 was of the original castle, before Xanatos' renovation.
Later examples have the number of windows vary, though their accompanying buttresses generally remain evenly spaced.
Should I, in spite of image #1 seeming to be the artist's intended concept, standardize the wall to have three windows and four buttresses, all consistently spaced, as well as matching buttresses on the opposite wall?
