Re: Thanos' bare hand
All we have so far is a face. So if the mo cap his body, it wouldn't exactly be a change, since that is where they would start.
In terms of his face, there is no reason for them to not do prosthetics to some extent. He looks great, especially in that last shot. I do think his eyes should be black with red pupils, but other than that, I think he looks great. His texture, the chin, he looks great. I'm just more worried about his bulk and height.
