Oil on board, 15 x 10 cm (= about 6 x 4 inches):
As I worked on this one, I took a series of WIP photos, which I planned on working into a YouTube video. I'll see if I get around to it. Unfortunately some of the photos came out thoroughly out of focus, so it might not be too spectacular. I can say this: there are few things that break one's concentration and "flow" quite as much as stopping all the time to take a photo!
