As it is 2000 years since Jesus was on earth, there is no one around who can say what he looked like. So obviously it has to be just an artist's impression. But he was a perfect man, so maybe he would be a very handsome person. He certainly would not be walking around looking like something the cat dragged in! As to the colour of his skin, well, he is everything to everyone If a black man drew his picture maybe he would have black skin - who knows. The main point is that he came to earth, lived and died as a human.
