First of all, thanks to all of you who commented and voted. A very special thanks going out to Gelert who selected it as a favorite.
Creature hit the nail on the head. The blur comes from camera shake and not motion blur. It was a hand-held shot and taken at the local zoo. This guy was actually sitting in the back of his habitat when we showed up, then he wandered out and I swear began posing for all the people with cameras, including a flurry of roars. Perhaps reminders to anyone thinking of jumping the fence to get a closer shot (well, it did cross my mind). In this shot he was actually stretching. I really liked that his hind quarters being in the air made the illusion that he was caught in mid-leap. This shot was my first to score above a 6, so I am very pleased with the results.

This photo creates good tension. Unfortunately not quite sharp with what appears to be lens blur rather than motion blur (going by the streaked look of the OOF background).
