I have a sketchbook that is about 3 feet thick and getting bigger everyday. But my painting process is really slow.  The ideas are there, but translating them into paint takes alot of time and thinking.  Time is something I don't have enough of, something I think everybody can relate to at some point or another.  Another thing with painting is that I need alot of concentration when I'm working on them and if I'm not in the correct state I cannot paint.  These sketches I did on an electronic drawing tablet.  When I print them they look different than on the tablet which is kinda cool because the hard copy is abit of a surprise from the original drawing. The lines are thinner and seem more expressive when I print them.
