Others who do not obtain consent will find themselves either behind bars or fitted with a fine. Graffiti artists try to portray their emotion on the canvas. Just as musicians, who put their feelings into their music, artists put it into their drawings. Each drawing gives a sense of what the artists may have gone through. Through the walls we can then understand what they have seen in their lives.
Some artists even leave messages along with their graffiti art.
Sometimes the message is about life and sometimes the message is about death. We all express our emotion in different ways and so do graffiti artists. Not only do these artists give emotions, they also give ideas to new and upcoming graffiti artists. They are there for new graffiti artist to learn of the past styles and maybe transform it into their own unique style of graffiti. Shapes and color of one individual's drawing may be different from another.
