Hi Doc -- A nice tight portrait of the Cheetah. Nice colours and looks sharp albeit i feel more DOF would have been helpful to get those eyes sharper. I might crop it a bit tighter coming from Rhs as viewed and also slightly from the top and bottom.
Beautiful details in the fur, nose and mouth sharp eyes sharpish ears not so, having said that I like the image and I like the composition. Just maybe consider warming up a little??
