A lot can be achieved by filing out the photographers comments. I helps us know or understand what you were trying to achieve when shooting this photo.
On first glance I was not fond of the angle of the composition as I find it to be a little to fast for the serenity of the subject. A polarizer would have done wonders for this photo as well and would have taken down some of the highlights or blowouts in the water from the overhead flash or sun. I would have like to seen this photo taken with a faster shutter speed to eliminate the milky look in the water as I find it takes away from the transparency. I also think you'll find it should make the photo more crisp/clear and not loss/lacking details as it is right now. I do however like the leaves bunched like that as that is the way I see it in nature and it gives a natural appeal to this photo. I think the photo may have had greater appeal if the water flowed from the right side top (instead of top right) to the left side bottom. It would have slowed the photo down and drawn the viewers eyes thru the photo slower creating a more pleasing feeling as it crosses the photo from right to left instead of top to bottom as it does now.
Good luck and keep shooting.
The water has a milky look to it due to slow shutter speed. In a closeup like this I think it would be better with a fast shutter speed to stop the motion and show off the clear water. Also the flash highlights are pretty distracting. Could you have cropped them out?
To me, the leaves seem a little too bunched. It's not easy to make out much detail at a first inspection. I like the way that the water flow is diagonal in the frame.
