When I was wondering how to draw simple car my friend told me that it can be done without much effort and pain. Many find drawing an inexpensive and simple hobby which offers great satisfaction and pleasure to the artist.
Drawing technique can be improved by practicing it regularly and using correct techniques. Even when learning how to draw simple car I was not able to draw smooth curves. Then my tutor advised me not to rest my wrist on the paper or canvas and told that when drawing any object any part of the hand should rest on the paper. Only the pencil should touch the canvas or paper while drawing simple car.
My tutor asked me to draw a simple car that I see instead of trying to draw a more complicated one that I know. It was of great help that I need not whack my brain to get the details of the simple car in the drawing form on the paper.
When learning how to draw simple car I also learnt that the drawing should have some depth and meaning in it. For instance if I had to draw a simple car in a distance I had to draw it in a smaller size than the one which is near by.
