Yeah, Starbie, it was mentioned way back when that the nails were press-ons, grown out a bit so you could see the real nail at the bottom/sides, which is why there is that space between the polish and the edge.
And of course you are right about the tobacco stains Victoria. I can see what you are saying too about her living a softer life, less need for age makeup.
And to Moni, I agree about Jack's eyebrows, and lines from frowning. It's subtle and brilliant in my opinion. I think he looks every bit the 39 year old. I also see how they made Ennis a lot more tanned in his face and hands as a way to show how he was always working outdoors. I think he is wearing some kind of wig in the final scenes, b/c his hair has this worn out, dry quality to it at the Lightning Flat scene and with Alma Jr at the end.
