Well timed with a good composition. I think the color and contrast hurt you a little. I see a little discoloration but that may just be some reflections.
I love that there is a ripple from the drop before but it looks like the drop in the air is already causing it. Beautiful shot, the spot on the left is a bit destracting but that could be clones out. Nice
A good attempt but being critical if you don't mind I think a greater DOF to allow the inner ripple to be sharp throughout would have improved it and the drop is a bit distracting but a good effort - good luck
