|I thought this was a very good image with nice eye contact with this cheetah on the move. It appears the light was a bit overcast in the original photo.|
In PS5, I did a basic upwards contrast adjustment and a bit more vibrance.
Then made a layer selection of the eyes to slightly bring out their color using a little more brightness.
Using NIK Color Efex, I applied a graduated neutral density filter to soften the lower portion of the image making the grass a bit darker.
Then I applied a bit of sharpening using NIK Sharpener Pro 3.0 (which really just uses PS existing sharpening with different plug-in controls).
Finally, I liked the overall composition but just cropped it ever so slightly and rotated clock-wise to better fill the frame with JeanMarie's beautiful image.
