It is always nice to see a tiger stalking. At the moment the top portion of the image doesn't have much details due to lack of depth of field covering that area. A narrow aperture like f8/9 or higher would have been nice as that would have meant more areas in focus.

The tiger and leopards are stalk and ambush predators. It is not easy for a tiger to manage to move close to deers without them seeing it. Tiger needs to be close enough to launch its sudden powerful charge and catch the deer unaware. Else, the deers are too fast. So too often we see unsuccessful attempts by a tiger in catching its prey.
