Watership Down and Ladle Hill: Drawing Pencil

I really wish that Derwent had come up with a better name for these lovely pencils. They call them "Drawing Pencils", or, sometimes "Soft Drawing Pencils". Which could easily apply to a 4B graphite, say. (Aren't all pencils for drawing with? Even the H family - which I generally shun - are intended for drawing. Very precise drawing.)

I don't think that there is any graphite in these pencils. They are smooth and waxy and come in a range of muted, natural-seeming colours (the range is quite similar to the Sennelier "Nature" box). I now have the tin of 24 colours, which I think is all of them. I already had the earth-toned tin of 6, which I used for Study in Yellow. It's nice to be able to hint at blues and greens, and I think that the full range of colours suit this subject, which is from a photograph taken at around 5:30 pm earlier this month, when the sun was on its way down and the hillsides were in shadow.

Here's a slightly earlier, sketchier version in the earth colours:

EDIT: There's a painting, too...
