I prefer the look of a front facing portrait rather than a side glance. Intentionally not looking at the camera while it takes a picture of you seems un-audibly visible. Its almost like, "dude, I know you see the camera, so why don't you just look at it?' Of the three photos of Jared, the front portrait conveys the most emotion and reality.
The concept that the left side of the face is more aesthetically appealing may be true, but I think it relies on the surrounding environment more. In the photos of Lena, I tried to see if I could make the right side facing photo deeper than the other two.
It's all about angles, and the looks. With Nathan, the right side of his face looks the best because he is looking intelligently or curiously at something. The left side photo looks plain and somewhat sad. Nothing interesting is going on.
