forgot to add that you should also post the cam settings used (shutter speed, f/stop, flash on/off, lens used, etc. so you can get more useful comments in the critiques. if it's easier to just post the exif data (copy/paste), then that'll work too.
if this was handheld, i think you did a great job at maximum zoom.
was this AF or manual focus? it looks as if AF may have targeted the fallen log instead of the the tiger's head, not really a surprise since she's mostly hidden behind it. the aperture of f/9 kept her head from being out of focus.
usually, i shoot zoo animals f/5.6-f/6.3. the wider aperture lets in more light.
as i said before, i like it. keep shooting and sharing.
Nice Picture has been taken,The tiger is a member of the Felidae family; the largest of the four "big cats" in the genus Panthera. Native to much of eastern and southern Asia, the tiger is an apex predator and an obligate carnivore. Reaching up to 4 metres (13 ft) in total length and weighing up to 300 kilograms (660 pounds), the larger tiger subspecies are comparable in size to the biggest extinct felids. Aside from their great bulk and power, their most recognizable feature is the pattern of dark vertical stripes that overlays near-white to reddish-orange fur, with lighter underparts.
