This is one of my digital painting I used a dark canvass. The setting is either dawn or dusk or a nighttime and it has an effect like the camera is shining the leaves and flowers of the foreground tree. You can just feel the coolness of the painting itself although it also has warm tones of colors in it.
Right now I am still practicing because I haven't had any experience in painting except being self-taught myself with the disposal or use of applications "Sketchbook" and "Paint3D" with my touchscreen Lenovo yoga which helps me create this kinds of art pieces.
