Im FINALLY finished with this window mural for a hot rod shop I have been working on for the past 2 months of my weekends. I had to do the whole thing from the inside of the window (so it lasts) . That meant doing the entire painting in reverse. I had to do the black outline first(that part was difficult cuz the black was not opaque at all and I needed about 3 passes to get it to be solid), then the highlights, then shadows, last color. It was a really fun project. It reminded me of painting cels for animation so long ago, its exactly the same reverse process.
