It's an illusion of perception caused by either the cameras or the human eye.  The human brain is the determiner of what is acceptable or not in human forms back in the hind-brain.  That is the reason that most human figures in CGI is immediately perceivable as false or defective humans.  It's a survival mechanism, that is VERY hard to fool.

So it looks for idealized mates, as well as defectives. People who are tall and well built and symmetrical are more desirable than people who are skinny or malproportioned .  That's just how the human brain appears to work.

Antonia is idealized, but to our minds as being more real than other proportions due to our hind-brains tricking us into believing it.  It's weird, it's strange, but it IS just an illusion that artists have been using since the Hellenistic Greeks stumbled on to it.
