The first photo below is the set-up I liked the most. The second photo is the same set-up as I began to draw. Can you see the difference (aside from a slight color variance, due to the exposure)?

The second view is from a much higher vantage point- from my actual eye level, actually. It turns out that when I took the first photo, I held my camera at chest height to eliminate keystoning (which happens when the sides of a photo angle in due to parallax). This, of course, lowered the vantage point. When I returned to start my drawing, and looked at it from my usual eye level, everything looked wrong! I was viewing the set-up from too high. I could, of course, paint it this way, but I much prefer the look of a lower horizon line. I don’t like the viewer to feel as if they’re above the table looking down. I remember now that I had a similar problem with my bricks painting. I had to lower the horizon line and redraw everything from a lower level.

I tried lowering my stool, but it wouldn’t go low enough. So, after marking everything’s position with a pencil on the tabletop, I removed the set-up and set about raising the table.

Fortunately, bricks are useful not only as the subject of a painting, but also as structural material. I have this handy pile behind my studio, which I find useful for both purposes.

They worked nicely. I also had to raise the spotlight an equivalent amount. All looks in order now. Next session, I’ll figure out how big the painting should be so I can order my canvas.
