The best way to flirt with a girl is to strike a chord with her feminine side. You can start the conversation by displaying your soft nature. You could begin by letting her know that her flowing tresses remind you of certain lines of a popular painting. An artistic comparison speaks a great about your personality as well. You will seem like an intellectual who is both creative and original. However, be warned that you do not get into the technical aspects of the painting, otherwise the conversation could yield negative results. For instance, telling her the phase that she resembles Picassos works from cubism may produce undesirable outcome.
