This image was done using Krita 4.4.3 with a Huion New 1060Plus.
Leon and Kiki invite you to join in the spring festival in their lands as they celebrate the joining of their hardware and software into one glorious kingdom of open source art. This is symbolized in their flag, as the metal framework forms the Huion logo, whereas the Krita logo is an image on the fabric. (The knobs on the ends of the bar are shaped like pen tips, as Leon’s tail is)
It seemed the best place to put Leon’s large tail was as a scepter in his hand. Kiki’s scepter is a silver paintbrush in her left hand, and her crown has three silver brushes, with faint glimmers of color in between like a color palette.
