Painting and sketching are the ways to express yourself. For some people it is their obsession, for others it is a way to relax their minds. While others consider it a way to make a connection with their inner-self. In any case sketching and painting are something intricate yet soothing and fascinating.
I believe that to display your art you do not have to be a great artist. You just have to draw you emotion and personality on paper.
Well..I always was a bad artist but I remember the pleasure that painting gave me when I was a child and went to school. I think it is really relaxing and helps to express yourself
