urban sketchers . tia boon sim 'i used to do a lot of black and white, quick, double spred sketches in moleskine pocket sketchbooks, hoever, I find myself creating more and more ink and watercolor sketches in a bigger format. this allows me to experimetn with different techniques. I find splashine the sky with blue, red, orange, and purple before adding salt for special effect a very liberating process. i am not restricting myself to a coloring excerise; I am experimenting and have no fear.'
