The Sultan's Favourite - stage 2

I have now put in some very rough colour to give me an idea of what works and what doesn't. The sky needs to be darker and I need to work out the colour of the shadows in the background palace buildings, these are the first things that I have noticed so far. I also need to make sure that the blue domes are a different colour and tone to the foreground pavilion and I need some touches of red in the palace buildings....and the foreground light areas should be more orange.
