Hi Timothy. You did a good job getting a sharp focus on the main action. One suggestion for shooting is to raise your iso. 200 is fine for still lifes and some landscape, but for wildlife and birds, higher shutter speeds are your friend and modern cameras and noise reduction software allow you to routinely use much higher iso values. As for the image, I think you may have tried to include a bit too much. I like the idea of the Wildebeest looking on or the Zebras’ apparent indifference, but both together just makes for a bit too much.
I’ve done a couple of quick alternate crops that you might take a look at to give you an idea of what I’m talking about.
