Do you have a special tip that you’d like to share?

Sometimes there’ll be something not quite right about a painting I’m working on and I can’t figure out what it is. I find if I look at its reflection in a mirror, nine times out of ten the problem will jump right out—maybe the ellipse at the top of a cup is uneven, the composition is not balanced or the perspective is off. Taking a photo of the painting with my cell phone and looking at it in isolation also can help reveal a problem.
