I love it. Makes me happy just to look at it. My only complaint is that the butterfly shape seems a bit uncertain of itself. Maybe brighter and with a bit less contrast, to make it stand out more from the mass of faces behind. I don't know. Would 9/10 be fair?
I was so happy with the good advice I got on my last photo that I'm submitting another of my very favorite portraits, a Cuban preschooler.
