This video demonstration is not at all complete. Nor was it actually intended to be a demo. However, it does show how to slop on paint to accomplish a goal.
It shows a loose approach where thing are suggested, rather than defined. In a world filled with high-definition photos and videos that are chock full of detail, loose paintings allow the viewer to use their imagination to fill in the blanks. Hopefully, this little clip it will help you to approach the paper without fear, and allow you to leave things out.
