First he was an impresionist painter but he prefered being a cubist painter with a very personally style. His principal preoccupation was the search of a new style by the opposition of the forms and the contrast of tones. From 1913 he developed a dynamic conception of painting based on the intensity of contrasts and colors. Most of his paintings have a cubist character, for example ‘Desnudos en el bosque’, one of his most import ants.
