Imagine a print by Ansel Adams. You're probably thinking of a black and white image, impeccably sharp and detailed, perhaps of Yosemite. Now visualize something by Monet. You're probably seeing a vividly colorful "impressionistic" painting, perhaps of a Japanese bridge or the French coast.
A lot of artists have a definitive style. You can see a piece and instantly know that it is an Adams, for example. Cultivating a style can be key to developing your own brand as an artist.
But you may also want to try something else.
