In fact I'm a designer, but you know drawing is totally different field from design area, so I take the drawing as an easy way to express, or a way of communicating with myself, the motive is simple, not improve any skill or show any interesting stuff, just draw random things and relax, like writing.
BTW i'm not good at drawing.
I appreciate those brilliant artists, they use brush to express their own worlds which are observed by their different eyes. Sometimes , you know, languages are too pare but only paintings are vivid. So good to be here.
