Congratulations Ben for posting something different, I am a great fan of all the antelope and the Red Haartebeest is one of many beauties available when the "Big 5" are not around
You seem to have captured this one at a moment of great relief, love the grass on the mouth.
I agree, more room at the bottom would be good and perhaps a too less saturation. All in all, a good looking image of this interesting looking animal. Great pose and grass in the mouth just right.
