One of the essential functions of art is to reflect reality and beauty. Art tries to capture and portray happiness and beauty, as well as pain and suffering, as they are, even better. Art reveals and displays the joy and sorrow that may be hidden in a glance or a smile. Art may travel to far-off lands and bring images of nature and stories of people. The artist constantly strives to improve her skill and ability, to use better tools, and to gain more experience. This will improve the quality of the work she creates. For the artist, art becomes a mission, and a means of worship. The artist seeks his existence and credibility in the beauty and/or reality of the work he creates.
