Good idea but the quality is suffering. It's soft, noisy, and the drop is blurry and cut off. Also the angle doesn't work for me personally. I would like to see the water drop falling down as it does naturally.
I tried to do this a month or so ago and after spraying 50 snaps of the shutter I probably had 2 that were somewhat decent, but neither was anything to get excited over. I appreciate what you went through trying to get this shot so I don't want to take a dump on it.
It's good to experiment though, this is definitely something you would need to manually focus, imo.
Try again if you get a chance!
