Leaves are a great subject for photography, and specialy as a desktop theme.
I have posted a few myself the last months. A leave can (as in this case) such a good texture, and when lit well....
"I never looked for it, gave it no name; yet I knew it always, when the gift of peace came. I stood quite still for the moment that it lasted...Then the light shifted slightly and the moment passed, leaving me...with the lasting echo of its presence.." Diana Gabaldon
Nice too, but I think in this case you would benefit from a lower perspective. That would further enhance the blurring and "leaf" the audience in wonder what this is.
