Yes, they did have a forge at that particular location of the building.
I will look into the individual bricks and perhaps add a monk bond animation, showing how the monk bond were staggered. But this will be a separate animation, also showing how the arrow slits works.
Would a 2D-animation at the beginning of the animation showing the monk bond as part of an arrowslit before the actual animation of the gate, make any sense? Perhaps as a 2D-drawing animation on the paper where I show the floor plan next where the building rise from the blueprint later?
Thank you for the idea of showing the actual mechanism of the drawbridge. Maybe that could be part of the 2D-animation.
I will add a soldier or 2 on the upper floor.
