Rubadoux primarily works on paper and canvas. His paintings are intensely personal glimpses into particular emotions, and he frequently speaks of his work as a journal. Greatly affected by his environment and a love of nature, Rubadoux’s painting style is colorful and fluid. But Rubadoux’s paintings are not literal documentations of nature, he seems interested in the essence rather than the facts of nature. There is an emphasis on line, color, and spatial relationships. Compositions are unusual in that the subject is seen hovering in a flat space and at eye level. While the subject matter varies, it embodies the artist’s personal conception of the world and his feelings and responses to that world.
