What kind of paper is in that magic sketchbook of yours? is it watercolor paper or just a heavy weight paper, but not specificly for watercolor. Also I see that your using a slanted desk. I read somthing about using gravity to help with making the color / water move. Do you find this true or not worry about it. Sorry to keep picking your brain, but your style is really clean and somthing to work towards. Cheers!
