Painted under the constraints of using only the preset tools and colors in the newest MSPAINT on Windows 10, without even using a tablet (point, click and drag), and I was very pleased with the result. Original 614 x 460 Pixels (4:3).
With this I explored watercolor-like effects of a soft bristle Sumi-e (oriental ink) brush in Corel Painter. I added some digital oil paint and pencil, and also did some hue alternation in Photoshop.
