Andrey- Christ: What did he look like?

For the longest time I have always thought what did Christ look like physically? Does it matter? Would my perception change of who he was and what he stands for? If he was the perfect man, as well as God, who would that perfection be displayed in him physically? Did people that saw him really ask those questions or judge him based on his appearance? Did his unconditional love for everyone and holy nature overshadow the question of his ethnicity or origin? Will science one day lead us to an accurate representation of his physical appearance? Are all the images of him throughout the world blasphemy towards God being all-knowing?
