Basic genres of his work: portrait, still life, landscape. He created drawings, theatre scenery, and a number of interior projects.
The period of early painting is characterised by works that are decorative, semi-abstract and expressive in form. In his later work, the form becomes more relief-like and the colour palette becomes richer and more saturated. He created an individual style of form and colouring with a strong Lithuanian mood. The works of the 1970s-1980s metaphorically depict the contemporary world, complex human relationships, emphasise the emotional element, with a lot of space given to improvisation, and the use of personification, symbol, allegory, and the grotesque is often used to make sense of the subject.
Most famous works include "Mother and Child", "Fish Sellers at the Seaside", "Woman with Fruit", "New Settlers", "Nude of a Woman", "Man at the Window", "Lithuanian Landscape", "Flowers", "Baltic Fishermen", "Midday", "Evening", "Woman with a Bird", "Brides", "People Looking at the Stars" (1973.), "The Little House in Viekšniai" (1933), "Nida" (1937), triptych in memory of M. K. Čiurlionis (1961-1962).
