Well I have to admit to being a little flummoxed as to how this came 79/92 because I thought it was a really clever and original take on the challenge... Maybe the title put some (though not all) people off but in photographic terms this was cool and weird
I like the idea but there really isnt anything to ground the image. I think a border would really help hold the image together--I find that my eyes are drifting away and there isnt anything to bring me back.
Likewise, i love how the leaf is B&W in a sea of color, but if you had put a little lower and to the right, it would fit better with the rule of thirds and anchor the image much better.
