Acrylic, pen, illustration board, unframed Original one-of-a-kind Although it is difficult to see the gold color in the image, I used gold acrylic paint and pen on a black illustration board to create the image of a quiet night. The image of the gold color changes depending on the lighting and the device used. Also, the color will change to a silverish color over time. Please understand this. I painted this work without any preliminary drawing, letting my hand flow through the work. I would be happy if you could feel the power of this work changing from day to day depending on your emotion of the day.
