I would agree the first processing looks too bright, but the second one seems too dark to me unless you're specifically trying to portray a lower light situation. You're also getting very different colors (not just saturation levels) which you can see in the colors of the grass.
It looks like there might be a mistake in processing the 2nd image because the background as seen between the cheetah's two front legs looks brighter and greener. It's as if a mask didn't include that when it should have.
