Is The Left Side Of Your Face More Aesthetically Pleasing?

For this assignment I had to determine weather or not the left side of the face is more aesthetically pleasing is a portrait. So, as you can see I have taken 3 portrait shots of my subject. One of the front side of his face, one of the left side of his face, and one of the right side of his face. In my opinion I feel  

that the right side of my subject's face is more aesthetically pleasing and I do not see much solidity in the argument of the left side of the face being more aesthetically pleasing.
