Not quite enough depth of field here, Could use just a little bit more of the subject in focus. It's admittedly tough at such a close range and an angle. Perhaps pulling back just a bit could help.
Just a bit more DOF would have added to the image. I can tell that the center of the leaf is focused, however it is such a narrow field of focus that it has the illusion of all being out of focus and I know that that is not the case.
