That's wild... the guy looks JUST LIKE the guy who owns and runs this little convenience store down the street from me...only he's a Saudi Arabian, and a little lighter in color. Something doesn't seem right about the nose. Maybe it would help you some if you picked out a particular person to model it after, preferably someone you can get pictures of from all angles and then use them for reference. African Americans do have a specific genetics to them as do all races, but at times it's kind of hard to pinpoint and often it's more in the skin color than anything.This guy seems to have a little too much red in him, unless it's the lighting, but that IS a really great texture.
