Like the pose and overall composition. Color on the cheetah looks muted in comparison to the green of the grass; think I'd up the saturation on the cat, especially to bring out the eyes more.
Yike! Look at the sideways feral glance this big cat gives! He/she really looks like they are sizing us up as it's next meal. Love the pose it is in - looks like it is waiting for the right moment to pounce. Details and lighting are great. My critique is that I think you could bring us closer to your main subject by either a closer crop or zoom to fill the frame with as much of this big cat as possible. Not only would it spotlight this dangerous beauty but it would make us feel & see that stare even more.
Some may not like the lack of saturation of the cat, but I really like the way it makes the animal part of it's surroundngs. I like the pose of this capture, too.
