It sure as hell doesn't look "mafia", and it falls pretty short of what I envision a "flapper" to be... It's a nice B&W, but as far as your theme goes - it's a failure.
maybe if he had a cigar in his mouth, with just a bit of smoke rising from the cigar?
XD
but I see how its "inspired" by these looks! the guns, her sequined top,...
however I don't see what the flower adds to the "flapper"ness of her look.
