Scratch that

Oil on canvas. Portrait not going well? Smear it out and scratch in some shapes. Skill: low Time: <1h Secrets: Muddy colour? Fix it in post! Comments: A reasonably fun way to salvage a disaster into something different. The effect is quite nice, and painting on a rough background gives lots of free detail. No nuanced brushstrokes required either - pick some cool colours, scrape in some stick figures and hope it looks artsy. Not one I'll hang on my wall.
