When a subject is placed as plumb centre as is the case here, using a diagonal line, especially having it placed just off the diagonal, is a good move in bringing interest and balance to the whole image. The lighting though is too flat. The yellow should be jumping up from the greens, even if it was taken in shaded conditions. Lifting the brightness and contrast would also give edge to the delicate water drops. If you are working with a program that has texture and clarity controls, try giving some mid range contrast with either of those.
An edit. My dislike of flat view forums increases. After I wrote the above I found that the lack of "pop" has already been addressed by others. While we have you here Alan, how is the move to a version of threaded forum coming along?
