The use of vantage point is fully in use in this picture of the ostrich.  Not only is the photographer taking a photo from a very close position to the ostrich but it it also taken from underneath.  This serves to make the ostrich's mouth all that more imposing and takes advantage of capturing the beauty of the sky as well as the heads of all the other ostriches in the background.  The photograph feels balanced between the bottome left and top right corners and between the top right and bottom right corners, between ostriches and clouds.  You can see so much detail in the in the ostrich's mouth and the hair on it's face that protrudes out from behind the mouth.  This is where the detail ends however and the rest of the photo is dominated by all that surrounds the ostrich's head.
