Picture the image above. The left figure is my original drawing but what happens if I mirror the artwork? It will become insecure and out of symmetry. If you are righthanded, the left image might look normal, if you are lefthanded, the right image might look normal. Why? Because of my handwriting. Lefthanded people and most people in Japan will see it! Sometimes the figure will show a contrary effect after correction. Drawings have a longhand too.
