Peter Poskas III paints landscapes and harbor views of Maine and Connecticut, intimate interiors, still lifes, and portraits of his family members. Using virtuosic yet delicate brushwork, he renders the changing light and time of day, the turning of the seasons, and the emotions of his family members; his work draws on the tradition of Edward Hopper, Robert Henri, and Rockwell Kent. Poskas also paints complex formal still lifes, often depicting objects that draw on his technical mastery, like small statuettes or intricately patterned china.
