I've made a lot of progress on this painting these last few weeks. I now have all six panels drawn out and the underpainting finished. I made some progress yesterday with the detail work on the first panel:I'm working 'wet in wet' for these, you can see in the following picture how I work just the light areas in first, and then fill in the darker areas around them. The tinted canvas makes it a lot easier to see what I am doing. Still have a long way to go - hahah.
