Great shot. The kids are really cute. What to do or change? Not much. You have the first child out of focus. It distracts a little. The viewer’s eye does settle there before moving on. The second child has the best expression. The background is distracting with all the clothes still in partial focus. Here I might have cropped in a little closer and just gotten the last two children. Otherwise shoot wide and then crop down. As is, the picture is fine street photography. I would have paid attention to the focus but at that distance the depth of field is not sufficient to get all three girls. If you shot more images I would have tried to get a more flat angle and had all in focus. But as is, this worked.
