I think your image demonstrates his ability very well. I would have liked to see a bit more room below and right since he seems to be moving rather fast.
Good job on the exposure and getting in the right place for the light. I like his strong shadow too.
Judy,
From the thumbnail, it looks like as if it is falling down. It seems to be moving down at a good speed. The f9 aperture covers the entire rock face. I feel that is a big bonus here. You got lot of details in the image. I like the diagonal composition. Thanks for sharing.
Cheers,

Neat image. Its interesting to follow the line of her hooves to see the barely visible ledge on which she's walking. Probably looks like stairs to them.
