That captures that 50s style quite brilliantly.
The profile views may be easy on the artistic requirements, but the hands are extremely difficult to get right even in that view. If you clean up, get your guy to do some ref shots together.
I don't usually repost, but today... I do.
Actually - to me the style in game is more 1940s than 50s. When you think about 50s you get those stupid drive-ins and poodle skirts and grown women running around looking like little girls. No thank you. The 40s had style, they had tailoring and it's just distinct and awesome.
