nothing precise. I spent a couple days sketching for concept and composition, maybe another day for the under-drawing, then maybe about 24-30 hours of painting time. About a week of solid work I think.
It's a basic grid with a repeating pattern, and the sides which are slightly angled are moving towards a vanishing point. I started by putting it down in pencil (how I start with everything in my paintings) and then putting an acrylic monochrome over top. I started in oils over that and worked just flat wall tones, then added the dark squares in wet (the acrylic showed through enough to see where they should go) and finished with the grout lines making sure to leave some lighter than others for more realism. The important part is a solid and correct drawing to start. Still kind of meticulous, but not quite as maddening as it looks
