If I ever learn to do great water action shots and find myself lucky enough to capture a splash the way you did, I will be...happy. Great shot, good job sticking with the challenge theme.
There are a couple of bothersome shadows from the water. Nice capture on the water and this is a nice water abstract. Seems a little out of focus/soft on the orange object being dropped which causes my focus to beome the crisp water but I keep going back to the bright color. Hope this helps. I'm just writing as I study it.
