Fact: The greeks made the first good looking male sculpt. It was freaking realistic. But then they realised that if u exagerate the little things on a human body, like muscles or buts, or any thing like that, like more longer arms and legs, it would have the best unrealistic realistic result. Like the people would look and say: WOW! that is nice, but it was unrealistic, tho they felt that it was remake of them. So it had its own gravity towards the people. That makes it Impressive, then a "silly" normal sculpt of a normal person.
Here:
Picture One: Fully Normal Human Body, all in good porpotions. Presenting all the muscles in action.
Picture Two: A full unatural human body. All out of porpotions. Muscles are not well represented.
So... But wich one is the most "attractive" one. I do believe that is the second one. (Also because he is in action, as in the first image the person is acting static, and not doing anything.) In the second image, the human body have strong unatural muscles. And the body is out of porpotions.
