On this chilly December morning, the oryx was probably maximizing his exposure to the sun. So it was not in a particularly favorable position for a shot. The full frame is below - the oryx occupies about 5% of the frame even at 200mm.
The goodness of the lens is revealed by this 100% crop. There is a fair amount of detail.
PS: Rajan Parrikar did some Photoshop magic. The main effect is from raising the color temperature, which makes the instant look like sunrise, with the corresponding warming of colors.
