I think it's really good, and probably the best CG of a real person I've seen. I'm very picky about these things too, but she does look more real and moves more like a real person than say, Hulk, who should really be easier to do since he's a monster.
And this is targeted towards viewers in the UK, where they are all familiar with Galaxy chocolate. If you're not familiar with it in the US, then it won't stick in your memory.
I think it could work with Harrison Ford as a younger Han Solo. If you've read the article in the original post, they initially had a stand in for Audrey whom they were planning to map the image over her face. However, because she has different facial expressions and subtle nuances, the actress would still not look like Audrey. That's why they went with a CG model of her in the end to be totally accurate.
In the case of someone like Harrison Ford though, he WILL have the same nuances, because he's the same person. He'll just be older. Same goes for other actors who are older as well whom they might want to recreate in their heydey. This would open up the way for an older actor to still play a role but to look younger, but they'd still be credited with the part even if they don't look as they do now. It's not that different ultimately from mo capping or even voice acting. They've just had their physical appearance altered, that's all.
But what happens if they wanted to, say, recreate someone like Kirk Douglas? Could they get Michael Douglas as a stand in? The difference between a different actress and a family member is that Michael would have many of the same nuances because they're either hereditary or he's learned them from his father as a child. Most children pick up the same facial expressions as their parents.
I think this could also potentially open up the possibility of having Sean Connery playing James Bond again (in a one-off) where he could look as he did in his heydey circa Dr No or FRWL. Would be cool to have another 60s James Bond adventure with him.
