Art
Zagraevsky's art does not belong to the classic primitive or naïveschools, since neither the formal nor actual parameters of primitive art are met. Instead, his style was best described as "primitivism", a genre which includes the "primitive" paintings of many artists who had an academic apprenticeship and extensive experience in other styles such as Paul Gauguin, Mikhail Larionov, Pablo Picasso and Paul Klee. There are some differences in Zagraevsky's style; his landscape paintings are "childish" in using a reverse perspective, the absence of chiaroscuro and the relatively accurate portrayal of parts. Zagraevsky uses predominantly open colours giving his paintings brightness comparable to children's painting. His paintings contain neither humour nor violence as these are not normally seen in the art of children. Since about 2000, Zagraevsky's works became slightly more generalized and varied while retaining their brightness. Details are drawn less carefully although the works remain "childish", with the hand of an experienced artist visible only in the stability of the stroke, the virtuoso technique of painting and drawing, and the compositional and the color balance. There remain recurring features in his art such as a "flattened" sun, squat trees with huge roots, multi-colored water, "album-styled" flowers and illuminated windows. In the 1990sBulat Okudzhava wrote of Zagraevsky:
