Louise IMO doesn´t look like Elisabeth at all. She´s the spitting image of her mother with the round face of her father whereas Elisabeth is a mixture of her parents with a tendency to her father. I think anyway that Mathilde and Phillippe could also be brother and sister. They look so similar to each other. I noticed earlier years ago that all the Belgian/Habsburg children look kind of pale and white-blonde and boring as children and becoming very pretty as grown-ups. Look at the children of Marie-Astrid and Christian Habsburg. Never ever believed that they would become so good looking.
