As GrauWeiss said, your usage of the same color works wonderfully for the photograph. It helps the view focus on the water droplets and blades. The vignette effect really helps with balancing the green out, though, I feel as though you could have left in a little bit more of that mid-tone green and taken out a little bit of the darker forest green around the edges. Of course, that may not have made the water drops stand out as much as they do currently so I say let it be unless you can easily go back and just play with it in your spare time. As it stands though the color balance is extremely strong.

I personally really like how you got the texture of the blades to stand out. That really knocks this photo out of the park. If those dots hadn't been there reflecting the water drops I don't think it would have been as strong. Beautiful yes but not as strong as a photo.
Something else I personally really like is the glare down on the bottom of the photo. Not only does that too help balance the photo but it mirrors the roundness of the drops. It also takes up some of the empty space down at the bottom making it feel a little less top heavy, though I have no problem with it being a top heavy photo. The subject matter of the photo makes that work.

As a whole this photo has a very strong composition and makes a strong impression upon the viewer. It demands the viewers attention and as a reward the viewer is granted a lot of little details that someone who just glances at it would not notice. Wonderful job.
