Nice sharp whiskers. That's what I always look for when I shoot a critter that has them. You may be already aware of this but in case you're not, a wide open lens with the tiger in focus will blur that foreground foliage. Here's an example I shot of a critter:
If you notice the eye of the great blue heron is sharp and the intervening foliage is blurred. This isn't hard to accomplish if you set your camera up to use the back focus button only. Disengage it from the shutter release. Focus on the mama tiger with the back focus button then, if your lens is wide open the foliage will be out of focus in the photo. In the example I provided I had to focus on the rear body of the bird then move the camera to frame the bird. When the shutter release is also the focus control the camera might focus on something you don't want to focus on.
