I believe that art is a powerful tool of expression and communication. You really have no walls in how you want to express something. You have no rules about how you want to send a message to the viewer. The fun part though is that sometimes different viewers will get a different message but with the same meaning. It depends from the point of view a person has but it's very interesting to listen to someone saying something for your art that you never thought of. That's why I love art, I just take a pencil and a white paper, everything else is secondary.
Sometimes I just draw without thinking, without having a concept in my mind but other times a have a strong feeling, a strong thought and I know exactly what I want. You see the muse of art, of inspiration can knock your door anytime, anywhere. Sometimes you expect other times not, but you always embrace her. That is for me the magic behind the arts.
