Yowza. An interesting look coming from a child. A bit freaky. Good focus, different and interesting subject. Not too hot about the brick background though. It's not too complimentary and would have been much better left completely out of focus to give just a soft yellow background.
I know that might not have been the intention but she is giving the same stare/pose as the little girl on "Night of the Living Dead" movie poster. I like the back ground, maybe would have been a nice touch to clone out hole in the concrete on the upper right corner, I feel it's distracting. The lightning is not bad exept for the shodowed eyes wich it give it a bit of grim look. I like a lot, I'm just not sure that was the intention looking at the shiny happy costume.
