Back Sketching

For years, mouse, stylus, multitouch & tablet successfully keep my hand away from traditional sketching tool: pencil & paper.
So I decide to start a hand exercise.
Got a sketchbook & Faber Castell Pitt graphite pure, sketching everyday in the office.





Though it's not that bad, my parents think that my strokes look stiff. "Too digital, dear."
I don't know what exactly does it mean, but I guess I have to keep exercising more & more.
