河岸上的靴子，炭笔只画了干湿交界

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.

炭笔静物素描，一双湿橡胶雨靴放在河岸平石上，旁边一根芦苇斜入画面。粗纸上用黑灰明暗塑造靴筒，靴面水珠保留白点，背景只用轻擦表达水面，近景低视点。
