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 your device. Please understand. Conscious of the beauty naturally produced by plants, living things, and cells, I painted this work in a flowing manner, leaving it to the movement of my hand without underpainting it. I would be happy if you could feel the power of this work changing day by day according to your emotions.
