About this pattern
A castle is architecture — straight walls, repeated crenellations, conical roofs — and it is the one subject in this set where the pattern works against the form. The Fish Scale cells are curved and offset, which softens edges that the building wants kept sharp. It is worth seeing precisely because the tension is visible. Fish scales overlap in offset rows, each curved cell tucking under the one above, so the pattern carries an implied direction and a sense of surface. On an animal it reads almost as coat texture, which is a happy accident of this subject. The curved boundaries mean no edge is ever rendered as a straight step, giving the softest result of the eight — and the loosest, since nothing in it is strictly aligned.
