Yeshuah was a descendant of Abraham, it is only in some paintings you see him represented that way, I have seen Jesus painted as black, japanese, white (yes with blond hair)..... I suspect your statement has more to do with your prejudices than facts.
Now as for paintings there has only been one artist's painting that have stuck in my head .... a little girl called Akiana, as a child she talked about God visiting her and eventually her parents became Christians. Her art is beyond what most masters attain after decades.
Here is the one she did of Jesus at 8 years old!

It is not what Jesus looked like, it is who He is!
Prof. Daniel B. Wallace (wrote the textbook on ancient Greek & Greek translation) in an interview in the book "The Case for the Real Jesus" says "It's disturbing that when it comes to the Christian faith, people don't really want, or know how, to investigate the evidence", perhaps you should try learning about Him.

Jesus: Man, Messiah, or More? (8-Part DVD)
Jesus has always been controversial. Ever since He walked the shores of Galilee and the streets of Jerusalem, the questions have remained the same: Was He merely Jesus the man, the rabbi-teacher? Could He have been Jesus the Messiah of Israel? Or, most controversial of all, was He Jesus the Son of God?...One group of scholars is trying to clear up the confusion. For more than 10 years, they’ve studied key events in the life of Jesus.
