Acrylic paints are used on MDF plywood. Several shades of blue and green were layered to express the color of the sea. You can feel deep colors within the gradations. I think the actual artwork looks more vibrant than the photos. Size: Approximately 10cm x 10cm x 6mm The surface is coated with Turner Clear Top Coat. The sides are also painted, so you can display it as is without framing it. There may be paint stains on the back from the production process. Please note that the colors in the photos may differ slightly from the actual artwork due to lighting conditions. I am working hard to create artwork using paints and brushes, as I want you to enjoy the analog texture that can only be felt by holding the painting in your hands (^-^) I hope you enjoy the uneven texture of the painting's surface and the depth of color that can be seen through the layers of paint. Thank you for viewing this painting from among the many works of art (*´︶`*) #Obi #Art #OneOfAKind #Interior #Painting #Picture #Original #Illustration #AcrylicPainting #ContemporaryArt #Handmade Obi #Blue #Green #TextureArt #Gradation #Beautiful #Sea
