Hi Frank, the first thing I saw with this photo was the date stamp on the woman's black skirt. Really easy to just get rid of that if you wanted to. But then I found the interesting part of the photo was really a middle grouping. More sophisticated editors would be able to clone the one child's feet and some more pavement, to improve further, but I'm not to that level yet.
After I cropped, I did an 'auto-enhance' and then sharpened the photo.
