Drawing and sketching on paper needs a different concentration in comparison with painting ...  the coordination eye - hand is more direct while the distance to the surface is mosttimes more less and the result is irrevocable. Drawing with pen and ink needs more preparation than sketching with pencil and a lot of experience. Painting in aquarel is the base for all painting -technic - from tranparance to more covered or mixing colours  . Using the right colours is a question of  exercising and inprovising . A combination of different technics give the expression more tension ... even working with sandstructure is always an adventure and give mosttimes a surprising effect ...
