Back again.
I did a little bit of healing, cos the rest is your job

you can see the outcome of that on the woman's coat.
Decided that the people needed lifting a little bit so I used the central point in a curves adjustment layer to brighten slightly. Used inverted mask to paint back in the people, avoiding the woman and child's face because I thought they were bright enough.
Used the High Pass filter to sharpen the people a little bit, with layer set to overlay I inverted the mask and painted back the people - lowered the opacity of this as well to about 50%. High Pass only set to about 1.
That was it really. The second image has been given a slight sepia tone in a hue/sat adjustment layer.
EDIT-I haven't done any work on the cars, buildings etc., in the image you may find that you want to touch up the few offending pieces that are there.
