I may be way off on my guesses, but ill take a shot.Obviously the diplomat takes inspiration off of Abraham Lincoln. That goes without saying.The spy seems to have a an appearance similar to Leeloo from "The Fifth element". Except the agent's hair isn't bright orange. And whats shown of her attire has me reminded of one of the Imperial agent's suits in SWTOR.Now the scientist...I want to say her looks are similar to Elizabeth from Bioshock Infinite...but I could be wrong.As for the Don...I seriously wanna say Al Capone, but the Don isn't nowhere near as pudgy as he was. There are alot of mafia figures I don't know of. I have no official answer, but all I can say is he looks like he was based off of one of the characters from "The Public Enemy".Now where I'm completely stumped is the Beggar and Officer.Aaaaand thats what I got. How'd I do?
