For me, it definitely PICTURE TWO. The smile on that kid's face is wonderful.
I am however with those who think that the selection method/criteria is a bit unusual. There are some great pictures that should have made it to the final but didn't for some reason. If this competition should continue, then the judges/panelists should be seen to be not only impartial, but also above reproach. My two cents!
Congratulations to the nine finalists and good luck!
