Aaww, this is a sweet image. She looks like she's having a wonderful time. I like how you captured her in motion, although I wish she was a bit sharper (easier said than done, I know).
Would have like to see the child worked on to bring out some more detail in the front. It appears a bit dark and loses some of the emotion created in the shot.
I am going to take a guess here...is this in Paris? Reason I ask is because I have never seen more grafitti infested newish vehicles in my life than when I was in Paris.
Now, about the image...it's good, a lot of story happening here. I would have edited a lirrle to brighten up the shadow on her face...but I like the moment you have captured 7
