"Overbite =/= Aryan teeth"
Fine. But would you say overbite = neotenous appearance?
Also, another thing I forgot to mention, the first heroine's jaw seems a little robust, irrespective of the gonial angle:
IMO ideally the jaw should be gracile as well in order to reduce its visibility, along with a good gonial angle. So the second heroine beats her in that department. I have noticed this in my own face: my right jaw bone is thicker than my left and as a result is more visible.
Sure, she compares favourably to the other two actresses in the picture, but not so much to the second heroine in the older message.
