Not sure what I'm looking at. You've got pretty good focus - I can tell there's water there - but the image as a whole isn't that appealing to me. Not sure why - other than I don't know what I'm viewing and that the colors could be bumped up a notch or two as well.
NIce colours. I think the subject (rain) you were going for is mostly out of focus where the action is. Also, this shot is too set up for my taste for a natural subject such as rain.
