There is a reason we are cautioned against making for ourselves graven images to worship. The true god is without substance or form. Therefore, I believe that Jesus was probably extremely handsome, and this was a major influence in getting people's attention. Since he was a carpenter, I'm sure he was very muscular and well toned. I would definitely stop to listen to someone who looked like Arnold Schwarzenegger but would probably bypass one who looked like a wimp regardless of what he was saying.
All people look different in every nationality.
I'm sure the Jews of Jesus' day also had different physical characteristics. I don't believe from a few artifacts and bones someone could determine what the typical person looked like.
