运河砖屋的屋顶，慢慢退回铅笔线里

One 3:2 mixed-media architectural illustration of a small canal-side brick house with a stepped gable. The lower two thirds are a restrained watercolor in burnt sienna and gray blue; in the upper third, the same roof continues into precise graphite construction lines on visible cream paper. One coherent building, aligned perspective at the transition, a narrow reflected strip of canal at the bottom, no annotation, lettering or watermark.

3:2混合媒介建筑插画：运河边一栋带阶梯山墙的小砖屋。下方三分之二是赭石与灰蓝的克制水彩，上方三分之一的同一屋顶延续为奶油纸上的精准石墨构造线。一栋连贯建筑，交界透视对齐，下方保留窄运河倒影。没有注释、文字或水印。
