"Technique is the escence of painting.
Discovering a techique that is an expression of the times is very important.
Street art and street painting are a technique.
Style is achived by repetition.
Themes are always similar through out history:
painting people, places, backgrounds is beautiful. 

How can you carry the big canvas? When you paint in the street?
Maybe you fold it into a roll.
When you open it the paint is printed on the other side.

Paintings are done in three steps. 
The paint is in the tube. Then the brush, and then on the canvas.
Four times, if you print the painting on the other side or the canvas.
Also paint on a sponge or a roll and then stamp that object on a surface."   Alvaro Andres Marquez
