|The strength of a candid id being able to capture a meaningful moment in time, when you only have a moment to get it technically correct. You've done that nicely.
The weakness of a candid shot is you can't choose all the elements in the enviroment. You can use 'darkroom' techniques for improvement, hoever, which you've done. That's where I'll keep my comments, however.
If I close my eyes and open them, the first place my gaze is drawn to is the high contrast patch of snow along the fence. There are no visual elements to lead my eye anywhere else, so I have fo force my attention elswhere, rahter than have the image guide it. The second spot that grabs my attention is the bright section of road at the top of the image. The difficulty is, neither of these two spots are the subject of the image. You'd like the viewer's attention to go directly to the child. To do that, I think you need to lower the contrast of the two trouble spots I mentioned, and increase the saturation of the child's coat.
The path and wooden fence are nice lines that would help lead the eye to the child, if it weren't for the two hot spots.
Just my opinions.
