I would have to say the most problematic part of painting is bi-direction/bi-split/bi-quadrant/whetever. Since this canvas is so small I just turned it around as I was painting the branches. No matter how hard I try, I just can’t paint the left side as well as I can the right side. O_o.
Anyway, I have one more of these small canvases, so I’ll do another one, and see if I can do better.
