These are wonderful action shots. The second is still a bit contrasty for my taste, but the action is spectacular.
The first shot is wonderfully captured, with nice tonal balance.
The 3rd is really something. I might consider a different crop to remove the distracting brighter water on the left, and also try to tone down the brightness on the tree stump.
But again, these are minor flaws in exceptional images.
You commented elsewhere that perhaps you tend to underexpose, or have a preference in that direction, accounting for the somewhat dark appearance of some images. A couple of thoughts there: is your computer monitor calibrated? If not, we may not be seeing the same thing on our various monitors, and this often accounts for differences that people see (in addition to whatever personal preference may exist).
And again, posting the shooting parameters, how, why and where the shots were taken, along with any relevant post-processing details, will make everyone's posts more informative and educational.
