I am drawn to dramatic architecture like a mouth to a flame. The more complex, the more mesmerizing! When I start to draw something of this scale, I begin with a rather central area of focus, and start spreading out from there. On this cathedral, my first lines were of the large second floor arching window. Once roughly in, I moved to each side, up and down. I am always checking those angles, the whole drawing is angles and how they relate to each other, just like a figure drawing. This constant checking keeps everything in scale, and the perspective true. This drawing is 1498 in 1498 days.
