These latest three are underexposed and a lot of each image appears to be out of focus. Also, it really is not obvious that it is rain, although I do see water and water drops or splashes of some sort. You might want to think about your composition and exactly what it is you are trying to capture. Perhaps, by now, you have begun to realize that photographing "rain" is not that easy, particularly if you want people to see "rain" when they look at your images. I would suggest that you might want to try searching the net using the phrase "rain photography" and see if tis gives you any ideas and you might also get an idea or two about how other photographers are capturing "rain".
