There are a number of different styles art takes. Some pieces are drawn, others are sculpted. Some are formed of glass and ceramics. In painting, there are two very separate schools of thinking. Realism is important for some artists. Other artists prefer to use representational painting. With
realism, objects are painted exactly as they appear in life.
Representational art is transformed by the artist into a color and shape to represent the object. The viewer then must decide what they are seeing and interpret the meaning on their own. Each of these is a valid way to create art and many artists experiment with both styles to find the one they prefer.
