Butte - stage 2

Worked some more on the sky although I'm thinking of introducing a bit of orange and pink into it as I'm trying to set the time to be later afternoon. Also made a start on the strata of rock below the butte using transparent paint mixes of Burnt Sienna, Permanent Orange, Ultramarine Violet, Winsor Violet and Transparent Oxide Yellow. The plan is all of the land in shadow will be in transparent paint, trying to introduce some variety into the colours used and the areas of rock picked out in the sunlight will be using opaque colour....that's the plan anyway.
