Excellent! I love the one or two falling snowflakes captured clearly, but it seems as if there are several more that came out blurred. Especially the big one in the front up close
I would have up'd your shutterspeed from 1/640 about 3 or 4 more stops and corrected for lighting with aperture.
I love it, thats a great picture that (to me) captures the innocence and wonder of children. I like the simplicity and contrast as well, with the black coat on white snowy background. Those few blurry snowflakes are a bit distracting but thats easy enough to fix, overall great shot.
nice shot! i dislike a lot of snow shots b/c the snow is so easy to blow out but this one is quite nice. i doubt you could properly exposure the snow being he is wearing a black coat lol
