There are many good aspects in this photograph.
First I like your composition. You filled the frame in a good way, well balanced. This image is also very sharp, which is really important for macro shots of plants. Your choice of DOF is also very good. All those leaves are in focus, while the background is blurried enough not to distract from the foreground. Well done.
The main flaw of this picture is that it is definitely overexposed in some areas. Not so much, but enough to be distracting. Too bad, I would have liked to see this shot with a different exposure. It is very disturbing in my opinion because the subject of this photograph is mainly the color green. This would have "popped up" more if the image was darker I think.
Anyway, besides that, this is a pretty well executed photograph.
A great bright green picture of leaves, but there's nothing really in the image to be interesting, no center of the composition or subject for it to be 'about'.
