The piece adds two different feelings because of the textures. The one on the left has a simple, calm, somber, intricacy to it from the details that make up the smoothness of it. The one on the right has more darkness, controlled chaos, eerie feeling to it, like it is going for the scare or kill of the one on the left. The artist put the two together and that makes the story. The textures of both raise conflicting emotions and it adds movement to the piece. The shading adds those textures.
