Since the previous post, I've spent about four hours glazing in dark shadows and smoothing out with semi-opaque mixes. I'm having so much fun that I think I'll do all again. It's surprisingly difficult to stick with many light washes and allow for proper drying time between coats. I've dug holes and troughs and had to puddle in fillings. It's good practice with repairs but of course it's best not to dig oneself into a hole to begin with!
