Before, during and after (but not there yet).
Taking into account that these are photographed in different lights, the colours are not necessarily accurate. The two directly above are today's "working back into it after a long break". I am playing with the idea that "all roads lead to..." and am superimposing the stylised roads from an old artefect depicting the area. At the moment I have become a little carried away with the flow and will have to set these back a little. What looks like snow will blend in better later. When I am happy that I have them right, and they are dry again, I will glaze with a sepia glaze to age them a bit. I am also flattening out the upper section apart from where I want to create flow down to the next stage. I will try to unite the backgrounds a bit more on the right hand side where the two images blend.
I have "cleaned my brush" under the arch to bring some of the colour down into the next section, and I will pick out the stones again later.
