Lighting is tough on this one. Looks like a simple flash. The image also suffers from a very thin DOF. By the time you get to the top of the sneaker, you are already soft in focus.
Looks to me like a snapshot. The lighting isn't especially good. I think maybe a lower angle would have worked better. I think maybe a crack due to a break would have more interest as well rather than one that's just between blocks.
I can see the crack and the stepping on the crack, but it isn't dramatic enough. I was thinking what if doing a low angle shot to catch the steping on the crack and in the backgroung see a 'mother' holding her back in pain.
The central object is a bit out of focus. The image would work better if it had been shot while she (?) was walking thus creating a more dynamic atmosphere. Would be even better to see the foot immediately BEFORE hitting the crack to create more tension: WHEN she steps on the crack, then...
