Same kid over and over, works well, since you're bringing out that her smile is so compelling, together with those eyes. Interesting work. I'm not entirely convinced I like it all the way, in particular because of what comes out as negatives at the far right edge (my mind doesn't get the why for that). It is interesting that you chose to put such a free smile/eyes into such a squared off environment, it is jarring in a way. I got to think about this one.
