Must post first. If choosing between the Post-Impressionists: Vincent van Gogh,
Paul Cézanne and Paul Gauguin, which one do you feel went in the
most interesting direction with their painting style and theory?

Paul Cézanne went in the most interesting direction with their painting style and theory since he reinvented and improved a structure that impressionists had abandoned; The light, shape, and color.

Explanation: These three painters were known for being revolutionary in their style. However; the one that I feel took an interesting direction was Cézanne. He didn't stay in the limitations of impressionism, and rather utilized a mixture between bright colors and juxtaposed brush strokes until he gradually obtained an expression of volume in his still life paintings, landscapes, and portraits. He was an uncomprehended artist, but he revolutionized the view of art.
