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.
For people who dont have talent in painting or sketching we dont relax our selves on it rather we are stressing our selves more in drawing or in painting

In my school before if they said draw the body or some of the organs of the body i hate doing it because i dont have talent in that thing .
