Ah I see. Well lets say we ignore the lighting or whatever from those prototype shots and just look at it side by side.
For me, I would say the prototype has a darker shade for the beard. It seems not as dark or striking on the sculpt I have.
For the wrinkles on the prototype, they seem to stand out more, possibly more shadows on the prototype than on mine.
Overall though, I would say its a good representation, possibly above 85% closeness in paint app. Im sure you can touch up the shadows and lines with minimum efforts.
Its not like Ned Stark's skin tone that resembles an oompa loompa. lol
