These are the ratings of the females by 3D Face Analysis. Four of them are taken in natural lighting conditions, presumably without any Photoshop enhancements.
People may not agree with each other on the ratings. It may be the result to different preferences. It also may be the result of differences in our ability to construct a 3D face from a 2-dimensional image. Some of us who see through makeup and Photoshop effects, may rate them lower.
These ratings may be biased because it does not control for skin exposure or clothing.
3D Face Analysis isn't attracted to buttocks, except in very rare scenarios. Even in these very rare scenarios, he isn't very fond of them.
