I think there is actually a significant problem with the generic European/ American visual depiction of Christ -- almost to the point that it can distort interpretation of Christ's personality.
Christ is almost uniformly pictured as a thin, meek, soft-spoken, pale, flowing-haired, gown-wearing hippy. If images are to be believed, He was perpetually solemn, silent, contemplative, gentile, and always cuddling with lambs and children.
This is a man that convinced people, by sound and sight alone, that He is the Son of God. He was a carpenter (in a time before power tools), and must've had a booming voice to command such respect. He was gentile when called for -- but this was not a meek person, and not the type of guy you'd have to check for an Adam's apple to verify His gender. He didn't look like one of the BeeGees.
Christ was a man. He was a carpenter ... so probably a man of substantial size and physical strength. His hands were likely rough. His voice must've been commanding, otherwise no one would've taken Him seriously. He was of middle-eastern heritage ... so likely not pale-skinned, and likely not with brown, flowing hair. He likely had facial hair -- but not the BeeGee looking getup that's often shown.
If I had to pick a modern person that I though looked like Christ likely looked -- I think Gerard Butler (of 300 fame) has the look down pretty well ...
