Petersburg. In the course of his education, Grinshpun absorbed the values of traditional painting, but at the same time he developed his own personal style ranging between realism and abstract. Grinshpun has never ceased to develop, deepening his style and technique with the use of original colors, and thus, his works considered to have an unexpected element. Grinshpun's worldview is well-reflected in his paintings- the idea of renewing the character of the work and the way of looking at it. His works are deeply emotional, a sort of poetic poetry on canvas.
