I was considering adding another layer--mostly to darken the foliage on the left--but decided against it because that area is already overworked, and I didn't think the paper could take it, either.
But I do like this scene, a photo I took this summer, and I would like to find a way to paint dune fences that, as the best paintings of them, imho, seem to do, bounces between positive and negative, sometimes painting the fence, sometimes painting what's behind it, so I'll be painting it again.
This didn't turn out the way I envisioned it, but I think next time I'll get closer.
The first error was I chose the wrong paper. Actually, I did four drawings--all subjects requiring wet, flowing washes-- on paper I pulled from a Kilimanjaro sample pack, assuming it was 140 lb, but once the paper got wet (and floppy and wouldn't hold more pigment), I began to suspect it was 90 lb.
My storm clouds started off too intensely blue violet. (Can't lay off the smalt!) Adding burnt umber helped.
I am pretty happy with green section, mostly with the little whites I left, though it could be darker.
