As a nonconformist artist, in the 1960s–1980s Flinta pursued informal creative explorations despite the ideological pressure of the communist totalitarian system. He allegorically embodied philosophical visions of his own universe in painting, graphics, and ceramics.

Flinta’s artistic language has no direct analogs. Constantly experimenting, he sought to depict space and plastic form through balanced proportions, expressive composition, and subtle tonal variety. At the same time, his restrained palette remained emotionally saturated. Through color, Flinta conveyed other qualities of the depicted world: weight, stillness, fragility, the constructive rigidity of material forms, and space. For him, composition, drawing, and preparatory sketches mattered far more than spontaneous impulses. His landscapes — whether marine, steppe, mountain, or urban — were united by his perception of nature as eternal, unshakable, and majestic.

With his works, Flinta invited viewers to reflect on the eternal, the mysterious, and the fleetingness of life, evoking unique states of the soul. “It is important that things and the world always promise to tell us something new,” — he liked to say.

Flinta created a gallery of portraits of his contemporaries that manifested the figurative system of his painting. These portraits are devoid of ceremonial solemnity — instead, they are painted in a lyrical tone that captivates with its sincerity. In these works, the echo of his monumental-decorative style gave way to softer forms, a flexible painting manner, and muted warm colors.

Ceramics held an important place in Flinta’s art. Here he drew upon folk traditions, which shaped the thematic variety and stylistic solutions of his works, particularly through the interplay of form and color.

Flinta participated in regional, republican, all-Union, and international art exhibitions. In 1974, he was awarded an honorary diploma at the International Ceramics Exhibition in Faenza, Italy.

His works are preserved in the Lviv National Museum, the Lviv Art Gallery, the Museum of Ethnography and Crafts of the Academy of Sciences of Ukraine, as well as in art museums in Sumy and Kemerovo, and in numerous other public collections and private holdings in Ukraine and abroad.
