The two photoshopped pictures on the sides are how the face should be, since Geralt is not a donut eating couch potato.
Edit: I forgot to give credit to one of our friends on the forums who posted this picture.
I don't think he looks fat in any of those but regardless I want to make a point in saying that both of us used images that where taken from the 35 min demo and that depending on the lighting in the scene and the angle he is viewed at he appears differently thin face to you or not. I make some comparisons to the trail video so I could show that the difference is as you say, so slight, but makes a considerable difference. though if you look at the comparisons I have made it is not consistently the case that this slight difference is considerable but varies again depending on the scene. he is just about identical in the comparisons, isn't that what you want? all the images I have used except one where from the 35 min demo.
another thing I want to say is that I personally enjoyed Geralt's model from the witcher one, if I had it my way I would see him in that form still because that is how I favor his appearance, and I think it is the case for many here that they have a particular way they want to see the character realized. that is not our choice though because the games are not our interpretation it is cdpr's and they should not be tailoring their vision to ours. surely as the creators what they think matters, ask them why did they use that face model. anyway we should be supporting cdpr to make their own choices not strangling them. some of the topics on the forum are so critical when one has seen their precious vision of the game damaged, what does that say about us?
