From Simon d'Entremont

One of my top tips for wildlife photography (which equally applies to pets, BTW!) is to capture or highlight a feature or behaviour for which the species is known. In this case, this species is famous for having a long neck and standing on it's hind legs to reach up for vegetation in trees that regular antelopes can't reach, going them an advantage in finding food. The shots I have with its face buried in the tree branches weren't very pretty, but this one as it was starting to go pull back to go back down was just right.
