Thanks for the facts Steve. We dont have anything at all that resembles these guys. The head looks like a donkey/mule, and the body of an antelope. Lovely pose from them both, and like the open mouths. Catching their breath from the run around. Well captured.
The open-mouthed poses are interesting and your explanation was helpful (and educational). :) I like the light. The animals pop from their background, but you still get a feel for their habitat. The shadows look OK to me. Well done.
Thanks for the interesting read. I think they are amazing animals and you have portrayed them very well here.
An inverse curve may help with the light.
