Removing People from images

I took a picture of people crossing a street and i uploaded the picture in to Photoshop. I made a copy of the image and i used the polygon lasso tool to select an image. I used the spot healing brush tool, and i also selected the "content aware" and "sample all layers" button.I used a medium sized brush and i started going over the selected image and then i selected the "Proximity match" button and i used a small brush and i went over certain areas that needed touched up. I used the "Proximity match" sparringly. I also used the "Clone stamp" tool to put in some of the background that was missing.

          The picture i took, i guess i could have chose a better area and time of day, because the sidewalk and street was different shades. some areas would be lighter than others and there was a lot of cracks in the street and sidewalk. When i used the "clone stamp" tool i would have to use a small brush and then copy a crack or different shade a little bit at a time. It took a while to do this project because of the different variations, but i think i did ok, but it could be better.
