You know I think that may be a neat shot, but it's really small so I think it's hard to tell. You might consider re-posting it with 800 pixels on the long side.
I like the details here, but the shadow dropping out is a little bothersome. I think that you should have diffused the light a bit more as well- really harsh shadows here. I also agree that a fuller crop of the leaf itself would add to this image.
