Artists should study the work of other artists. Compare your paintings to artists who are better than you, and dont become complacent. Study books about the great masters and hold the reproductions of their works right up next to your efforts so your weaknesses and strengths are apparent. Keep a scrapbook of paintings you see in magazines to refresh yourself with inspiration. Constantly check out other artists Web sites: The Internet is one of the best things to happen to art. And finally, go to museums to study great artwork every chance you have. Nothing beats seeing a painting in person.
