 Towards the end of his life, Dimitrescu began expanding his palette to cover more somber colors, while exploring compositions in which the background was stripped of details and usually of a dominant white.He died in Iași and he was buried at the Eternitatea Cemetery.Most of Dimitrescu's paintings take inspiration mainly from the life of simple folk, and especially from that of Romanian peasants and miners; they attempt to portray Romanian traditions and way of life, drawing on his encounters with both Byzantine art and the work of Paul Cézanne.
