河岸上的靴子，炭筆只畫了乾溼交界

Charcoal still-life drawing of wet rubber boots on a flat riverbank stone, a reed entering diagonally. Black-gray tonal modeling on rough paper, reserved white droplets on the rubber, lightly rubbed background suggesting water, close low viewpoint.

炭筆靜物素描，一雙溼橡膠雨靴放在河岸平石上，旁邊一根蘆葦斜入畫面。粗紙上用黑灰明暗塑造靴筒，靴面水珠保留白點，背景只用輕擦表達水面，近景低視點。
