Tower of Babel - stage 4

Worked some more on the sky although you can't particularly tell from this photo. It's nearly finished but might need a few glazes, I'll decide tomorrow morning over my breakfast coffee.
I also painted in some darks into the foreground bushes and grass as it's quite tricky to work out the tone of the colours that I will be using on the mesa, too dark and it will come forward too much, too light and it will lack the sense of scale I'm looking for.
