Collage is a great way to get new ideas. Juxtapose, and pay attention to texture and color. Combine and recombine to form new relationships.
1.) Make choices and collect prints and photographs of content and subject matter that appeals to you. Choose both environments and specific content. You can choose atmospheric things like fog, and weather too.
2.) Cutout silhouettes and your own shapes from your clippings.
3.) Finally draw, alter, add, and reflect shapes and form. Draw new color palettes, and work with the color palettes present in your clippings. Use media like graphite and colored pencil. You may want to begin a new painting with gouache or watercolor.
