Artists & Illustrators magazine - Summer In The City fourth day

I have now put in some darks so that I can gauge how light to make the sunlit surfaces and how dark to make the shadows on the buildings. I am leaving the shadows alone and will come back to them when I have all the dark areas in. I want to try and get across the dazzling light of a summer afternoon, everything else is subordinate to that idea. That blue sky is the wrong colour too!
