15 STAY LOOSE
While such advice can help to create strong images, if they ever become restrictive I throw out the rules and do some unstructured sketching. I use bigger, looser, bolder strokes and shapes and then go back to these tips. In the end I never want to lose the spontaneity in the image, otherwise it loses its fun. If making the art isn’t fun for me, it won’t be fun for the viewer.
