This drawing was made due to I remember while I was living in New York in the 80's and going to work with the temperature five degree below. I used to sketch everyone that used to ride on the bus, until one day someone came to me and broke my sketch book on my face.
I stood there for a while looking at the person speechless. Then I realized not everyone like to be photographed or sketched in public.
However, my luck changed the next day because I was offered an assignment by a good friend of mine to paint a flower vase with a special shining paint made in China. I knew I needed a needle-like brush with a hard tip. I went to my paint box and took one of the thinner brush I had and put some paint on it and brushed it off with thinner. I did not clean the brush with soap and water to make sure that the next day the brush was hard like a stick and at the same time usable.
