The theme, or harmony, of a painting can be created by any one of its visual elements. A single colour... repetition of shapes... Light can be a theme.
Mike SvobThink of the centre of interest in a painting as you would read it in a novel or see it in a movie. The crisis or climax is that point when you simply can't put the book down or wouldn't dare leave the movie, for whatever reason.
