Waiting For The Sun - stage 5

Apart from painting the distant sky and landscape through the arch I spent most of the day working on the canyon wall at right, trying to work out the colours I want. I can see in my mind's eye that the right hand side of the picture is mostly greens to provide a complementary contrast to the yellow orange light coming in from the left, but have had some difficulty in working out the right kind of green that I am happy with.
