I thought it looked like Lenin.....no one else saw that? As others have said, the lighting works well. I don't know how close this is to the original photo (the closer it is the lower the score it deserves), but at the very least I'm guessing you haven't made it worse. Its a good, sinister Lenin in my mind (and he was in many ways a sinister man, so it works on a character level).
Maybe a slight Brando resemblance, but not in my mind as strong as Lenin....sorry if this isn't what you were aiming for....hahahaha
