Expressive Watercolor Washes. Abstraction. Composition. Shapes (geo-morphic). Colors (harmonies and contrasts). Texture. Layering. Juxtapositioning. (See Gude.) Tie thematically into felt qualities of an experience, music, dancing, dreaming... Look at Aboriginal Dreamings (dot paintings), Miriam Shapiro (I'm Dancing as Fast as I can), and Miro or Kandinsky. Watercolor painting fun, but is much harder to do well than you think.
