Whatever you put on paper evokes a response from your viewer-often quite different from the reaction intended. Consider the skills required to manipulate watercolor around on a piece of paper with a brush and then add the aspects of art in general, such as composition, perspective, line, tone, color mixing and many more.
Watercolor can be a simple idle entertainment or a very complex discipline.
The best way to master complexity is to divide it into conquerable sizes and conquer the smaller skills one at a time. Some of these smaller pieces will be called working on wet paper, working on dry paper, composition, line, tone shadow, detail, mixing color, painting faces, painting figures,landscape, seascape, urbanscape, abstracts and many, many more. A Way to Draw on the Road to a Painting Use basic shapes, block in the layout. Block in with lines, circles, ovals, squares, rectangles, triangles, cones, cubes and spheres. Make any corrections and don't bear down too hard on the pencil at this stage of the drawing.
