For me the winner is pure portrait - tells me something about boys' characters and has no social commentary which is why I place it higher .

I was not certain Assorted Toppings told me enough about the individual because it has the secondary theme of a social commentary. 
Maybe it does say all there is to say about this Muslim  woman living, and selling ice cream, in a secular society but I can't help but feel that there should be something more. Perhaps if there had been someone at the counter she was interacting with her own personality could have come through.  Perhaps that forlorn look to the horizon and isolation says it all ?

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
