A finger painting done with the Artrage oils digital app which I think is free through Google. I use it on my little android phone. Two tools, a brush with four varieties with a sliding size bar and a pallette to choose colours from and the ability to to change the effect from non metallic to metallic. It’s quite a challenge to draw with a tool that smears and smooths out the surface as you draw on it. I enjoy it because you get such a different effect from other sketching apps.
