I was drawing while wondering how much the flow of the lines would affect the viewing experience. By letting lines from all directions settle on the screen, it becomes possible to show the lines themselves. Depending on the expression, this can be a hindrance. This was the case for me in the past. For the past few years, I have been uncomfortable with showing the lines. However, I have a feeling that if the lightness of the lines is appropriate, the lines themselves and the lightness and darkness can be presented equally.
