Actually it's stage three as I forgot to post where I had got to yesterday. I have now roughed in the clouds and made a good start on the buildings - I have left the actual citadel as it is for the moment as I feel I need to have another look at it over my breakfast coffee tomorrow. I am wondering if I need to introduce a little variety in colour in the buildings so I will leave it for the moment. It isn't actually coming out how I intended but that's OK as I quite like the look of where it's going - it kind of looks like a sandstorm coming in which is quite appropriate as the location is Egypt...
Colours used so far: Phthalocyanine Turquoise, Winsor Violet, Pale Violet, Burnt Sienna, Permanent Orange, Naples Yellow, Yellow Lake Deep, Winsor Yellow, Lead Tin Yellow Lemon and Warm White.
