Well, I'm still chipping away at it to see if I can get it closer. Have to go asleep now for what is going to amount to a 'nap' before work. But tomorrow when I get a chance I want to see what it looks like if I square the chin (currently it's kinda rounded and less defined than it is in the reference pic) and also see if he needs the asymmetrical jaw that Arnie has where it's smoother going up to his ear on his left side and more angular on his right. In theory not essential but sometimes it's the weirdest things that really bring a likeness out.
