How old you "look" doesn't mean much. I'm 20, but people were guessing that I was 25 back when I was 17. Recently I grew a goatee and now I don't even get carded.
Beyond that, I think most people have a difficult time guessing the age of other races. I want to hear how old some Dominicans think he is.
In that picture, he sure looks 20 years old to me.
