Your "good" side is more science than pose. Scientists at Wake Forest University showed research subjects photographs of 20 male and female faces taken from opposite angles. The participants uniformly found the left side of the faces more appealing than the right.
Since the brain's right hemisphere is better at signaling emotion than the left - and controls the left side of the face - facial expressions tend to be stronger on the left.
Perhaps that's why iconic paintings like Vermeer's Girl With The Pearl Earring lead with the left side.
Which photo of Angelina do you think looks better?
Science says the one on the right!
