As an artist he remained a difficult figure to place; there are few painters with whom to compare him, and he does not fit into any school. His early affinities were Neoclassical but his style can be described as Neo-Rococo. After his death, his painting fell out of favor, being considered romantic, glossy, and superficial. Little was known about him personally and his art was not taken seriously until recently. However, a major exhibition of his work at the National Portrait Gallery (United Kingdom) in London and the Petit Palais in Paris in 1987 brought him into the limelight again. His paintings are exhibited today in leading European and American museums.
