It is painted with acrylic paint on paper. The design is an on-the-spot idea. I tried to make it simple and impactful. I am not very good at explaining my own expression in words, such as statement or concept, and when I try to express something in words, I feel as if I am being forced to say it, which makes me feel depressed, If there is a concept behind this painting, I would say that it is a simple design, with a simple composition, so that when it is displayed, the work emanates impact, or presence, or something like that. It is framed.
